Research progress on non-precious metal catalysts for proton exchange membrane fuel cells
Starting from proton exchange membrane non-precious metal catalysts,the research progress of metal nitrogen carbon catalysts,transition metal oxide catalysts,and transition metal sulfides catalysts were summarized.This article focuses on the methods and applications of Fe-N-C catalysts and their element doping modification,structural control,and stability control,and elaborates on their deactivation mecha-nism.Finally,the future research directions of proton exchange membrane non-precious metal catalysts were discussed.
