Abstract：Fuel cell vehicle （FCV） is a kind of new energy vehicle with zero emission. In recent years， major engine plants have started the basic research and development of FCV. In this paper， a fuel cell stack （80kW） air supply system parts are selected and simulated. The maximum current of the stack is 500A， the control flow is 107g / s， the pressure ratio of the air compressor is 2.47， the efficiency of the humidifier is 26.1%， and the cooling power of the intercooler is 8.45kw， and the butterfly valve with diameter of 20 is selected as the back pressure valve. According to the performance data of parts provided by parts suppliers， the air supply system is simulated and analyzed. The maximum current condition and NEDC condition are simulated. The results show that the fuel cell air supply system can meet the requirements of type selection according to the calculation method in this paper.
