▎ 摘  要

Proton exchange membrane fuel cells are promising candidates for a clean and efficient energy conversion in the future, the development of carbon based inexpensive non-precious metal ORR catalyst has becoming one of the most attractive topics in fuel cell field. Herein we report a Fe-and N-doped carbon catalyst Fe-PANI/C-Mela with graphene structure and the surface area up to 702 m(2) g(-1). In 0.1 MHClO4 electrolyte, the ORR onset potential for the catalyst is high up to 0.98 V, and the half-wave potential is only 60 mV less than that of the Pt/C catalyst (Loadings: 51 mu g Pt cm(-2)). The catalyst shows high stability after 10,000 cyclic voltammetry cycles. A membrane electrode assembly made with the catalyst as a cathode is tested in a H-2-air single cell, the maximum power density reached similar to 0.33 W cm(2) at 0.47 V.
