The main disadvantages of the fuel cell system from domestic suppliers were summarized as following: 1) fuel cell system having lower output power with lower efficiency; 2) Fuel cell stack having lower power density; and 3) Air compressor development lag behind. Therefore, research and development work for domestic fuel cell system should be focused on the following aspects: 1) to enhance the fuel cell stack power output and the performance of the air compressor to greatly improve vehicle performances by operating the fuel cell system in the high efficiency area; 2) to optimize the
