摘要： In a polymer electrolyte fuel cell of the present invention, at least one of electrodes comprises conductive carbon carrying a platinum group metal catalyst, conductive carbon carrying no catalyst metal and a hydrogen ion-conductive polymer electrolyte. The preferable amount of the conductive carbon carrying no catalyst metal is equivalent to 5 to 50 wt % of the conductive carbon carrying the catalyst metal. Incorporation of the conductive carbon carrying no catalyst metal to the catalyst layer enables reduction in potential concentration on part of electron conduction channels in an electrode, whereby an electrode for a polymer electrolyte fuel cell having an excellent life characteristic can be provided.
