Characteristic of power systems of fuel cell vehicles and performance improvement

The paper generalized the progress on the fuel cell vehicles gained by several famous companies in the world. Based on the fuel cell power's features different from the conventional systems fed by oil, the paper studied the methods for selecting electric motors, transmission systems and control strategy. This paper predicted that an alternating current motor and the integrated driving system would be the most outstanding mode to occupy a vast market. A view of the technology for the fuel cell vehicles in future is lined out.
