In order to solve the air pollution caused by internal combustion engine and the energy exhaustion problem. There are many researching to overcome this problem. Fuel cell is a device to convert the chemical energy of fuel into electric energy. Hence. Fuel cell can obtain higher efficiencies than combustion engine. The low emission of pollutants and high electric conversion efficiency make this one of the most promising candidates for a very wide range of energy sources, to electric vehicles. In this paper hybrid system which is consist of PEM fuel cell and battery was tested. When this system need drive torque. battery did that work, and PEM fuel cell power was used to drive the car with constant speed.
