The fuel cel stacks from domestic suppliers and international suppliers were compared to develop a durable and reliable fuel cel system for domestic fuel cel car. The main disadvantages of the fuel cel system from domestic suppliers were summarized as folowing: 1) fuel cel system having lower output power with lower efifciency; 2) Fuel cel stack having lower power density; and 3) Air compressor development lag behind. Therefore, research and development work for domestic fuel cel system should be focused on the folowing aspects: 1) to enhance the fuel cel stack power output and the performance of the air compressor to greatly improve vehicle performances by operating the fuel cel system in the high efifciency area; 2) to optimize the system operation condition and the material properties of key components to greatly improve the stack power density; 3) to realize operating air compressor under low pressure for low power output, and high pressure for high power output; 4) to elevate the air compressor surge line to operate the air compressor with high efifciency and high rotation speed.
