Fuel Cell Cathode and a Polymer Electrolyte Fuel Cell Having the Same

摘要

A fuel cell cathode comprises a catalyst layer comprised of a catalyst-supported electrically conducive carrier and a polymer electrolyte. The catalyst-supporting electrically conductive carrier further supports or has mixed therein a catalyst that is in contact with an oxygen absorbing/releasing material. The cathode has excellent electrode characteristics with respect to oxygen-reducing reactions. A polymer electrolyte fuel cell fitted with the cathode can provide high battery output.
