Abstract: : Fuel cell is widely used in the field of new energy vehicles, and its output performance is greatly affected by operating conditions. The paper combines the results of the test rig experiment to build a fuel cell simulation model and designs a simulation experiment scheme to analyze the sensitivity of the operating conditions. The results show that the operating conditions such as inlet pressure, inlet humidity, stoichiometric ratio, and stack operating temperature all have a certain degree of influence on the performance of the fuel cell. Compared with the anode, the sensitivity of the cathode operating conditions is higher. The optimal range of operating conditions for the fuel cell is explored, providing reference for the design and performance optimization of automobile fuel cell.
