According to GM, the HydroGen4 is more dynamic and functional compared to previous models: its propulsion system was optimized in particular. Its fuel cell is made up of 440 cells connected in series. The whole system allows a power of 93 kW and feeds a synchronous electric motor of 73 kW/100 hp. The acceleration? The 0-100 km / h in 12 seconds. Its autonomy is 320 km. GM HydroGen4 has a storage system consists of 3 tanks at high pressure of 700 bars made of carbon fiber they contain 4.2 kg of hydrogen. This alternative has the future ahead of it!

The Ford Ka Hydrogen Bond

You know that the new Ford Ka compact is unveiled at the Mondial de Paris (see article). Well this small city car has a green star movie! In the new James Bond Quantum of Solace entitled to be released on October 31 2008 in the United Kingdom and France, you can see James Bond (Daniel Craig) and Camille (Olga Kurylenko) at the wheel of the Ford Ka Hydrogen Bond with a fuel cell with hydrogen, revamped for the occasion.

The manufacturer Ford Ka explained that the Quantum of Solace was unique with a metallic gold paint and interior and exterior design exclusive: it has been imagined by the Center Style Ford Europe, in collaboration with interior designer Denis Gassner rewarded with Oscars. Its technical characteristics are disclosed in a few months. Meanwhile, James Bond is going to undress shapes its gaze generous, as usual!

Associate Professor of Tokai University, CEATEC Pavilion in industry-university exchanges Electrodes for fuel cells conductive CNT / PTFE composite membrane technology introduced

Electrical and Electronic Engineering, Faculty of Engineering of Tokai University associate professor Yoshiyuki 2008, September 30 – October 4, in the Makuhari Messe (Chiba City) was held in a comprehensive cutting-edge IT and electronics exhibition “CEATEC JAPAN” (Combined Exhibition of Advanced Technologies) in the Pavilion’s industry-university exchanges, electrodes for fuel cell technology as “conductive CNT / PTFE-coated metal composite membrane separator to the development of” Introduction to the exhibition.

Associate Professor polymer electrolyte fuel cell electrode (separator), a carbon nanotube (CNT) and fluorine resin (PTFE) complex consists of a conductive coating film by the electrode surface to prevent corrosion of the fuel Improve the efficiency of the batteries can power. In addition, the membrane electrode coated with a direct-type fuel cell (DMFC) that can also be applied.

Polymer electrolyte fuel cell, a membrane electrode complex (MEA) across the hydrogen and oxygen to generate electricity by chemical reaction. Voltage, MEA between the two sides of the carbon electrodes arises. The new electrode (separator), and the extraction of electricity, hydrogen or oxygen supply on the part of the MEA.

Performance verification, the stainless steel electrode “conductive CNT / PTFE composite film,” If you do not, and if there are comparisons with.

Open circuit voltage of the fuel cell, “both of 0.8V and a film seen by RARETAKATTA change,” he said.

On the other hand, fuel cells and increase the output from the current, both of which have reduced output voltage, composite electrode coated with a film that can suppress the decrease, the membranes that gave the maximum output of fuel cells, 2.7W (The film is not, 1.7W), and the effect has been confirmed. The “conductive CNT / PTFE composite membrane,” the MEA and fuel cell electrode inside the electrical contact between the resistance and a decrease in the fuel cell’s internal resistance was reduced according to the analysis.

Typically, this electrode (separator) materials, metals such as stainless steel is used. When the fuel cell power generation, in the vicinity of the electrode, causing the water, and fuel cells from the inside to be acidic, metal corrosion by the MEA and the higher the contact resistance is a problem. The CNT and the electrode coated with PTFE composite material by way prevented corrosion has devised.

“Conductive CNT / PTFE composite membrane”, respectively, in water distributed in advance and how to disperse a mixture of liquid has been fabricated. CNT is that a strong cohesive, CNT dispersion solution for the distribution of cellulose is the addition of auxiliaries. PTFE and mixing ratio of CNT, CNT concentration (weight percent) and more than 10 percent, to improve conductivity and also make sure that the (PTFE, the extremely low conductivity).

The coating on the glass substrate, the film fired at temperatures of 350 centigrade, high mechanical strength, acid and sulfuric acid corrosion, but not in the mood to see. In addition, the contact angle of water and 110 degrees, and is hydrophobic.

This time, “conductive CNT / PTFE composite film” made of stainless steel electrode (the effective area of 40mmx40mm, thickness of 1mm. Pore diameter of 3mm to 23 locations opening in the structure) coating on the surface of the fuel cell has been created (Hole, the supply of hydrogen and oxygen to the MEA).

* MEA: complex membrane electrode
Electrolyte fuel cell membrane electrode and, in general, as a joint production of the complex. That is, each of the three-dimensional structure respond by interfacial reaction to a change in velocity, the individual can not be manufactured. Such a complex, in general MEA (Membrane and ElectrodeAssembly) call. MEA, the polymer electrolyte fuel cell membrane electrode used to call complex parts, NAFION (electrolyte) membrane supported on both sides of the platinum catalyst thermocompression carbon fiber structure of the electrodes.

2009 home sales in April published a fuel cell, Tokyo Gas Co.

Tokyo Gas, 2009 April (tentative) from the sale of fuel cells for home use “ENE FARM (ENEFAMU)”, October 7-10 was held at Shinjuku Park Tower, “Life Design Exhibition’08 , “Was published. The fuel cell system and the impact on the environment as well as the large-scale stationary fuel cell demonstration project to apply advanced fuel cell has set up a family with the adoption of the cases presented to the panel.

Oct. 7-10 was held at Shinjuku Park Tower, “Design for Living’08″ exhibition (Photo: Tokyo Gas)

ENEFAMU “fuel-cell unit” consists of two units. Fuel-cell unit, removing hydrogen from city gas, a chemical reaction with oxygen in the air to generate electricity. The chemical reactions that occur when using hot water to build and earn. Made of electrical appliances in the home can be used in the water bath, shower, kitchen and hot water use.

Patterns of energy demand at home as a data storage will continue to function. Therefore, the lifestyle will be combined with energy-saving operation. The amount of power, such as tanks installed in the kitchen to check on the included remote control. Suddenly need a large amount of hot water when the heat source to be backed up by aircraft.

Power is supplied from a combination of electricity and water heaters compared to the traditional family in general, the 31 percent reduction in energy consumption. Energy utilization rate improved to 41 points from 37 percent to 78 percent. CO2 emissions will lead to a reduction of 45 percent. This 2kw-class residential solar power generation system when installed, and is almost the same effect.

ENEFAMU of Tokyo Gas, the company’s Panasonic is made by Ballard and Ebara. Is roughly the same specifications. In the case of Panasonic products, the size of the fuel cell units W780 x D400 x H860mm,the unit W750 x D480 x H1883mm, both weighing 125kg. The installation space and a width of 1.2 x height of 3.3 x depth of about 2.3m will be required. The price will be around 3 million yen. The country will get a subsidy from the user side, so the actual amount paid will be about 200 million yen.

article in the current prices are approximate. We determined by the amount of aid from countries where the product price and the amount of the burden on the user side, until the release may change. Tokyo Gas was the overture to supplement it.
