Fe-N/C catalysts for oxygen reduction reaction supported on different carbonaceous materials. Performance in acidic and alkaline direct alcohol fuel cells
Fe-N/C catalysts for ORR prepared using Fe-phenanthroline and different C-supports. Weight loss during pyrolysis and C-disordered phase amount affect the ORR activity. ORR activity is more influenced by C-support in acidic than in alkaline conditions. Influence of C-supports features confirmed by acidic DMFC and alkaline DEFC tests. Durability in acidic DMFC and alkaline DEFC was assessed.
