Advancements in the study of Fe/N/C materials as cathode catalysts in proton exchange membrane fuel cells
Beginning with the mechanism of ORR,this article integrates the preparation and application of Fe/N/C materials,analyzes the mechanism of efficient oxygen reduction electrocatalysis of Fe/N/C mate-rials from the perspective of active sites,and elaborates on the stability issues encountered in the develop-ment of high-performance Fe/N/C materials.It further proposes suggestions and prospects for the applica-tion of Fe/N/C catalysts in fuel cells,providing references for the future development of Fe/N/C materi-als.
