Fuel cell is believed to be the third generation power system after the steamer and the internal-combustion engine, with the virtues of high efficiency, low noise, low emission, reliability and stability. Fuel cel have been developed as the main power of UAV and light airplane, or as the APU of a large passenger airliner. In this paper, a DC motor system is proposed, which is driven directly by a Proton Exchange Membrane fuel cel . A Matlab/Simulink model is used to simulate the dynamic characteristics of the fuel cel and the motor speed. The work here can be applied to help the design of the fuel cel powered flight vehicles.
