Abstract

Carbon materials containing Fe coordinated by N atoms (Fe-Nx moiety) embedded in the surface have been attracting much attention as noble-metal-free oxygen reduction catalysts for polymer electrolyte fuel cells. A carbonaceous thin film containing N-coordinated Fe and Co was formed from Fe and Co phthalocyanines on the basal plane of highly-oriented pyrolytic graphite to fundamentally investigate the effects of the addition of another kind of metal. An increase in the oxygen reduction current was observed for the carbonaceous thin film compared to those containing only either metal, suggesting the synergetic effect of their coexistence.
