Submarines: Ideal fuel cell vehicle

 

Fuel cells apparently make a good submarine hard to find. While fuel cell automobiles promise reduced emissions on land, the high seas have long enjoyed a virtual amnesty from air-emission regulations.

Emission-free on the Alster: Since August 2008, Hamburg-Visitors to the “FCS Alsterwasser” ecologically correct on the central waters of the Hanseatic City of sail. Makes it possible to combine electric and fuel cell: The energy comes from a hydrogen tank, up to 50 kilograms may be – that’s enough for four days. From the hydrogen produces fuel cell then electrical energy for the motor.

The company’s latest line of U212 and U214 Class non-nuclear submarines have been developed using a silent operating fuel cell plant that runs on nine 34-kilowatt Siemens polymer electrolyte membrane (PEM) hydrogen fuel cells. An air-independent fuel cell propulsion (AIP) system provides an extreme increase in underwater endurance, increased diving depth and overall efficiency.

The development will push the Hydrogen Bus Alliance. Partners of the merger include the cities of Berlin, Hamburg, London and Madrid. Between 2009 and 2011 counts Melczer because of the twinning with a demand of more than 50 buses, from 2011 to 2013 should be 100 and in the years 2013 to 2015 will be 500 buses.

The U212 combines a conventional diesel generator with a lead acid battery and an air-independent propulsion (AIP) system for silent slow cruising, and a fuel cell equipped with oxygen and hydrogen storage. The system consists of nine PEM (polymer electrolyte membrane) fuel cells, providing between 30 and 50kW each.

The U214 submarine, still in development, has a displacement of 1,700 tonnes, is 65 metres long and is manned by a crew of 27. The propulsion is again provided by a Siemens Permasyn engine which draws its power supply either from the fuel cells or from batteries which are fed by a diesel generator. Performance of the AIP system has been increased with two Siemens PEM fuel cells, which produce 120kW per module and will give the submarine an underwater endurance of two weeks.
