In the high-altitude environment, the thin oxygen and low atmospheric pressure diminish the net power of the proton exchange membrane fuel cell (PEMFC) system. In order to solve this problem, a net power enhancement strategy (NPES) for high altitude is proposed. Based on the close energy interaction between the system and environment, the PEMFC system model for high altitude is established. The oxygen excess ratio (OER) optimization trajectories for variable altitude environments are derived by conducting net power characteristic tests of PEMFC system in various high-altitude environments. Based on this result, a sliding mode control is used to realize the net power enhancement of the PEMFC system. Tests are carried out on the constructed RT-LAB semi-physical platform for validation, and the results show that the NPES proposed in this paper can improve the net power of the PEMFC system under variable altitude conditions.
