Patent ID: 7977014

Claim:
A polymer electrolyte fuel cell assembled by stacking a plurality of single cell modules each comprising: a polymer electrolyte membrane member; an anode electrode formed on one surface of the electrolyte membrane member; a cathode electrode formed on the other surface of the electrolyte membrane member; first and second frame members which sandwich the periphery of the electrolyte membrane member, and a pair of separators which sandwich the anode electrode, the cathode electrode, and the first and second frame members, wherein the first and second frame members are arranged laterally outward from the anode and cathode electrodes so as to be laterally spaced apart from the anode and cathode electrodes by a clearance, with part of the electrolyte membrane member being exposed, and wherein the second frame member includes a plurality of through-holes positioned along the periphery of the electrolyte membrane member, the through-holes being arranged such that an opening of each through-hole abuts against the electrolyte membrane member.
