Description

ABSTRACT:
This invention provides an electrode for a polymer electrolyte fuel cell which fuel cell contains: a solid polymer electrolyte membrane; electrode layers formed respectively on both faces of the electrolyte membrane; two reinforcing members which cover respective outer surfaces of the electrode layers; and a sealing member which covers, extending from respective end faces to respective end parts of the reinforcing members, whole peripheries of the two reinforcing members, wherein the electrolyte membrane, the electrode layers and the reinforcing members are integrally formed by the sealing member.
