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.
