Abstract: In view of the current situation that commercial test platforms for fuel cell stack cannot meet its R&D and test requirements, e.g. its air and hydrogen supply systems cannot fulfill the functions such as active regulation on the air humidity and voltage of fuel cell stack etc., a multi-functional fuel cell stack test platform is developed based on the outcomes of years of research of the fuel cell research team in Tsinghua University. The platform can not only accurately provide the fuel cell stack with a wide range of operating conditions close to the real operating conditions on a vehicle, but also realize the output characteristics of fuel cell stack required by the research, owing to the active regulation function of anode and cathode outlet pressures and anode / cathode dual recirculation function added.

Key words: PEMFC, test platform, anode/cathode dual circulation
