In recent years, with the continuous enhancement of fuel cell power, hydrogen supply systems have been evolving towards blind-end anode topologies with hydrogen circulation. However, research on testing systems for hydrogen supply and circulation lags noticeably, particularly in the performance testing of core components such as hydrogen circulation pumps and injectors. Therefore, a multifunctional testing platform for fuel cell hydrogen supply systems is developed in this paper, enabling component testing, characteristic data acquisition, offline calibration, and other functionalities for hydrogen circulation systems with different configurations. The platform, by simulating the pressure drop, hydrogen consumption, and the production of water and heat in real fuel cells, mitigates the additional cost incurred by testing on the performance and lifespan of actual fuel cells. Ultimately, based on this platform, an anode pressure control and anode purge control test are conducted on the hydrogen supply system of a 150 kW fuel cell, verifying the capability of the developed testing platform to meet specific testing requirements for different loads.
