Story of Nissan X-TRAIL FCV

The ultimate environmentally-friendly vehicles are called, is a fuel-cell cars = FCV fuel cell vehicle. Hydrogen as an energy source, and in the air in a fuel cell to react with oxygen, and get electrical energy. Reaction between hydrogen and oxygen to the are and take the “water” clean-only vehicle. Until now the environmental impact of the car and less than overwhelming, but right now I want to spread the car, but still have many hurdles.



Nissan X-TRAIL FCV

Breakthroughs should be a lot of challenges in the future given the mobility of cars on the undoubtedly important. So Nissan is currently developing a test ride in the X-TRAIL FCV, including infrastructure, tried to track issues.

The dawn of the now departed FCV ceremony methanol reformer
In 1996, Nissan to develop fuel cell vehicles will start in earnest. Until then, the concept was announced and the technical, but the real action FCV cars of the 1990s as a starting point to say. In 1999 and started testing the vehicle. At the time, followed by financial difficulties have been developed in the MENAKATTA still in the development of the technology to determine the future of survival were considered.
RUNESSA vehicle at the time of the FCV based on the difference between now and reforming methanol fuel cells for expression.Quashi reforming methanol extract hydrogen fuel cells, how to use it, many automobile manufacturers Tricor. However, this method should present the FCV has almost disappeared. That improved technology Quashi difficult to extract hydrogen, and that will take time to start the neck. Quick-start the car and asked KAKAWA were successful, removing hydrogen reforming the Quashi, I would have been a time lag.





RUNESSA was based on the FCV. Methanol reformer at the time was a ceremony mainstream fuel cells

Based on the Xterra FCV. The current high-pressure hydrogen is the dominant expression

The automobile manufacturers from around the use of hydrogen to the vehicle itself, the current went on the style of FCV. Nissan as well, in terms of business partnership with Renault of France took five years to start a joint development program. At the time, had been sold in North America based on the Xterra was developing FCV high-pressure hydrogen-style. The United States in April 2001 and based in Sacramento, California, the highway has started running experiments.

V-shaped recovery and the birth of the X-TRAIL FCV

In 2002 the Japanese government and, finally, FCV to a full-fledged research and development, conducted by the Ministry of Economy, Trade and Industry JHFC (Japan Hydrogen & FYUERUSERU demonstration project) started. Nissan also participate in JHFG course, the same year in December, leading to the current X-TRAIL FCV FCV to have been born. The products and technologies, recycling and environmental protection efforts of the mid-term environmental action plan decided, “Nissan Green Program 2005″ was because of the backing. Nissan’s V-shaped recovery will be realized.


The first X-TRAIL FCV

The first X-TRAIL FCV equipped with a lithium-ion batteries, and low-pressure hydrogen tanks for the 350 top-class performance. But the bottom line UTCFC fuel cells made by the United States. It was used by Ballard’s fuel-cell technology, but did not disclose any of the companies would have been better off UTCFC, but it is the heart of its development of fuel cells was a long-cherished wish of the Nissan.

To develop its own fuel cell

Its development of fuel cell in December 2005. A stable financial health, Nissan has returned to power to realize it was happening. In Yokosuka, Kanagawa Prefecture, Nissan Oppama (Oops PAMA) in the factory test track in a test ride and had just published a fuel cell research facilities. Both the manufacturer in this area only in the most advanced technology, development of the site to publish was unprecedented in the unusual.




Oppama plant in fuel cell research facility in 2005, when the public. These unusual to public facilities in the state this photo of the car are to evaluate the stack

Large single cell Evaluation of the low temperature at the time and equipment. Announced in August 2008 of the new Honda V Flow stack stack, as well as by the use of metal separator performance. Even in sub-zero temperatures to start with the plan said. In the winter of the season demonstrated in laboratory experiments Rikubetsu in Hokkaido, seem to be




Fuel cells and the polymer membrane is the heart of the test separator is also

This year over such research, its high-performance fuel cell stack is made

The exterior of the X-TRAIL FCV was announced in the 2003 model and does not change much, but the contents of attention. Developed in-house fuel cell stack has been the biggest topic. The size of the stack and 03 made by UTCFC equipped model than the stack, the smaller what is about 60 percent are successful. In addition to power generation capacity of 90kW to 63kW and is greatly improved. The maximum speed of 150km / h to improve. In addition, this model of the high-pressure hydrogen storage tank is 15 percent smaller in spite of its stack made to improve efficiency in power generation, 370km achieved over the range. This fuel cell vehicle at the time of the top rank. News of the stack with its development and at the same time, Nissan 700 and the pressure of the high-pressure hydrogen tank will be mounted. This range is 1.4 times the previous increase to more than 500km. And a range of practical issues were also on the end.



Nissan announced on August 6, a new fuel cell stack developed

Vehicle testing about 10 years from the start of the first test ride again in the X-TRAIL FCV

Ride in a Nissan X-TRAIL FCV is a long time, the Nissan headquarters in Ginza gallery, as usual, came without a sound. Precisely because of the rain on the test drive, loaded with tires churn up the water to hear noise is not silent at all, compared to regular gasoline and overwhelmingly peaceful. Is obvious, such as engine noise and exhaust sound, not sling oneself in front of me stopped running.



The streets of Ginza emerged in the X-TRAIL FCV

The predecessor based on X-TRAIL (T30) remained essentially announced in 2005 to model and the mechanism has not changed, he said. And to turn on the ignition system to start in a moment. The stack is abnormal and there is no leakage of hydrogen systems are checked, but most ended up in the moment before the start of the preparation time to be almost equal to that. Even gasoline from the car started to change rider is not uncomfortable. However, you can start a “READY” illuminates the character to remain silent. Hybrid car engines start even if you do not remain silent, but there is no such person in the car that exposure remains a quiet car will be a surprise.




Turn on the ignition system from the start until the next screen

After a moment, the instrument panel to the “READY” lights of the characters

However, it often only hear sound coming from the car. This is in the air compressor in order to send the sound of a fuel cell. As noted earlier, the hydrogen and oxygen fuel cells are electrochemical reaction to the system. In order to supply oxygen in the air compressor is not sent. D in the normal range as a lever to select the accelerator choose, as most push forward without sound. Depending on the accelerator of meter rise in the power of the instrument panel. On the accelerator and go Torque and jerk to accelerator to find out. Big torque at low rotational motor can accelerate the typical sense. In the sense of acceleration is extremely smooth, even acceleration on the accelerator operation is not uncomfortable.




A vehicle information display screen. However, after the system starts running before the start of the state. Batteries and fuel cells to power the catchment

When you start running, the power meter to rise

The car in the city’s noise around the large, self-car sound system not hear the most. Unfortunately the rain when it was test-driving, driving on the sound system is almost drowned out the sound could not confirm that. FCV so quiet that it’s running. When you test drive before the track was dry, so the sound of the compressor from the inverter and other high-frequency sound to be heard slightly, but could not confirm such a high-frequency sounds.

I ran faster and faster capital region would not complain about the acceleration performance. Frequently it the accelerator to accelerate the response, RAKURAKU overtaking is also accelerating. A long-term acceleration of the motor torque is unique. Heavy vehicles are heavier for the ride is a little hard to feel that, in common use, and the problem seems to be in such terms. If it is practical and what seems there is no problem once it’s completed. But, hard as the car approached the car market is to some extent, the infrastructure for the supply of hydrogen, another hurdle is high.

The charge of hydrogen fuel stations in the future I see

Currently the development of the automobile manufacturers are competing in the FCV, many of them are using compressed hydrogen. JHFC hydrogen stations in Japan and also to build infrastructure has been verified. Hydrogen station near the city center in a six-place fixed, mobile and two hydrogen filling stations. These different types of hydrogen stations, and the Senju hydrogen station, LPG (liquefied propane) gas or city break type Quashi extract hydrogen. This is your interview, Ariake hydrogen station to the storage of liquid hydrogen to be sure, but compressed hydrogen gas to supply the type FCV.



Ariake Hydrogen Station

Ariake hydrogen station near Odaiba, Showa Shell Sekiyu K.K., and is run by Iwatani International. How hydrogen stations and hydrogen supply, depending on the type of the two main groups. “Offsite type” is called a hydrogen station is made out of hydrogen, the type carried by tankers. “On-site type” called to the station, such as gasoline and LPG Quashi Kai, the type that produce hydrogen is in place. This type of off-site coverage will be provided at Ariake hydrogen station, Senju hydrogen station type, such as on-site.





Liquid hydrogen tank. Occurred in the coke furnace steel plant, “deputy prime water” is carried, will be stored here. 10000L in volume, about the pressure in the tank is kept to 0.3MPa




Look to the left of the box unit of liquid hydrogen booster. Will be supplied from the liquid hydrogen tank and booster to 40MPa. Then, in the center of the carburetor, gas and liquid hydrogen. Right photo, below minus 253 ℃ liquefied hydrogen is supplied through the pipe

Ariake hydrogen station, occurred in the furnace of steel, “deputy prime water” is used. This is a liquefied station. Liquefied gas and new energy to be used, but still carry the gas is too bad because it is efficient. However, the filling of liquid hydrogen in the FCV (emphasis) to have a loss. Return liquid to gaseous hydrogen, and up to 350 compressed air pressure in the process lost 20 out of a few percent. These losses will have to lose. And the station also important to reduce construction costs. The use of hydrogen in a variety of laws and regulations or not, and the result has been a rise in costs by 2015 the construction of hydrogen filling stations to reduce costs to 200 million yen is the goal. The current gas station construction in tens of millions of yen compared to, it still shows a high hurdle. This hydrogen station is expected to take one, which is a good way to verify that the current phase. The number of hydrogen stations tend to just have to look into the current phase of a proven, the next step is still ahead.




Vaporization of liquid hydrogen booster when you go to the recovery of the compressor BOIRUOFUGASU (left) and the accumulator machine (right)



In the hydrogen station, in addition to the accumulation of knowledge management, the ministry of natural resources and low-carbon demonstration experiment. Because of the accumulation of data, or a panel of the dispenser, as well as the amount of hydrogen filling, liquid hydrogen pumps and hydrogen power consumption in the amount of loss appear

Another important how the hydrogen is produced. FCV is the ultimate eco-car, but creating hydrogen from fossil fuels are not a true Eco. Such as solar and wind power generation using renewable energy to produce hydrogen is not required. Of course, in a period of transition from fossil fuels to produce hydrogen that could have no choice but to use renewable energy in the future it will be necessary. The ultimate in solar cells and wind power and hydrogen to create a self-generating, private cars and hydrogen filling (filling).

Nissan FCV will be the next generation?

This year, the first time in eight years in Japan summit was held (Summit). The 34th Summit, July 7-9held in Hokkaido, but the auto manufacturers to environment-related technology and a series of new fuel-cell vehicles in the announcement. Nissan X-TRAIL and clean-diesel is sent to the, FCV did not talk about.
After about a month from the summit on August 6, announced the new fuel cell stack, and at the same time in 2010 and to introduce a new hybrid electric vehicles (rear-wheel drive), has announced a new lithium-ion batteries. After a month on September 5, the world’s first SHIRIKONKABAITO (SiC) devices for use in vehicles has to barter. EV FCV as well as a series of related technology has advanced. In particular, the conventional fuel cell separators made of carbon change from the thin metal of the performance. The volume of the stack from the traditional 90L and 68L and the much smaller, 90kW output from 130kW to improve rapidly. In addition, the amount of platinum used in 1 / 2 and at the same time to reduce the durability of catalyst is also increasing. It’s worth noting the future, this new stack and a new lithium-ion batteries, SHIRIKONKABAITO (SiC) devices used in the inverter, is the introduction of next-generation FCV.
FCV is currently based on the next generation of Nissan cars and has been selected to stage in the near future with new models such as the stack is likely to appear. A stack of high-performance X-TRAIL than that of a large vehicle that can be used, so the introduction of the new Murano FCV may be. FCV still in the research phase, but the turning point in 2015. The hydrogen station in 2015 to move to a commercial phase.

Antares DLR H2

The research aircraft Antares DLR H2 is the world’s first bootable, airplane pilot with fuel cell propulsion. It is based substantially on the last few years built boat Antares 20E. In two additional external load containers will be the fuel cell system and the hydrogen tanks under the wings for increased appropriate. In further steps could the performance data of the plane with up to four external load containers and more advanced fuel cells still significantly increased.

Developed and built the high-flying testbed project partners from Long Aviation in Zweibruecken. As the primary source of energy for propulsion is one of the DLR Institute for Technical Thermodynamics specially provided fuel cell system. This system is nearly identical to that used in aircraft fuel supply system for board and provides the electrical energy for the Long Aviation developed powertrain, from the power electronics, motor and propeller exists. The use of a highly efficient fuel cell (efficiency up to 52% electrically) with the hydrogen fuel makes driving this airplane CO2 released. The waste product is clean water.

It is expected that the pairing of the fuel cell with a very quiet and powerful electric propulsion small plane in comparison with piston-driven engines set new standards in the fitness level requires. The project impresses by bringing together interdisciplinary activities. To a very economical flight to allow the entire aircraft is technically optimized flow. The goal is turbulent air currents in all areas to be avoided.

Long Aviation, the company is making a long-standing experience with. The integration of the experimental vessel was both aerodynamically aeroelastic both a challenge by the solid experience of the Institute for Aeroelasticity of the German Aerospace Center, an optimal placement of the containers can be achieved. This is the dynamics of the airplane is not affected. The additional air resistance on the Antares 20E model series are less than 15% and with a potential additional burden of more than 200kg.

When the coupling of the fuel cell powertrain system with the new routes were also begun. The fuel cell system was designed so that it directly with the engine control unit can be connected. The components and saves costs and increases efficiency. Therefore, both the Institute for vehicle concepts of the DLR as well as the Bern University of Applied Sciences Biel and the Long Aviation an important contribution. A subsequent hybridization with a lithium-polymer battery will power the aircraft continue to improve. The result is a high-tech makers of a variety of architectures of fuel cell systems can absorb. These can then be luftfahrtrelevanten conditions such as pressure, temperature, acceleration and vibration tested.

For the first flight at the end of this year, a fuel cell system in cooperation with the firm BASF Fuel Cell GmbH (electrolyte + electrodes) and Serenergy A / S (Stack Subsystem) for the airline upgraded. That was at the Institute of Technical Thermodynamics alongside overall system architecture design and build a whole range of temperature and pressure measurements.

With a specially designed control architecture Algorithm shows this is a very good weight / performance ratio, an important criterion for the airline. Upon completion of the first tests, which are aimed at a maximum altitude and thus a minimal negative pressure to reach the fuel cell system developed for maximum efficiency in converting fuel energy into electrical energy to guarantee. Now the entire fuel cell system used and the hydrogen tank weigh about 100 kilograms. Thus, only half of the additional burden exploited. This offers a high potential for the aircraft for possible flights record (height, width, etc.) compartment.

To make a comparison to be able to stand further fuel cell systems and architectures prepared to your airworthiness to be investigated.
