Abstract
In 2007, we started research and development of a demonstration long-range vehicle to cruise 3000 kilometers. It is important to improve a system performance of a fuel cell system and to improve storage methods of the pure hydrogen and the pure oxygen to achieve this aim. It is necessary to install an oxygen tank on the vehicle because the oxygen is not taken from environment in the sea. A large quantity of hydrogen and oxygen need to let the fuel cell system generate electricity for a long time to cruise at 3,000 kilometers. Because energy efficiency becomes worse if the body of the vehicle becomes big, the gases must storage compactly. We are developing a pressure vessel for the hydrogen storage, metal hydrides and an oxygen storage system.
