Abstract:
1. A composite membrane, comprising: a plurality of membrane electrode assemblies, disposed in a planar arrangement, each membrane electrode assembly including an electrolyte membrane, an anode provided on one face of the electrolyte membrane and a cathode provided on the other face of the electrolyte membrane; and a plurality of interconnectors containing conductive members, each one provided on lateral faces of the electrolyte membrane disposed counter to each other in a neighboring direction of said membrane electrode assemblies, wherein said interconnector includes a support portion protruding toward a central region of the electrolyte membrane on a cathode side of the electrolyte membrane, wherein the support portion is in contact with a cathode-side surface of an edge of the electrolyte membrane, and the electrolyte membrane is held by the support portion, and wherein an angle α formed between an electrolyte-membrane-face-side surface of the support portion and a lateral face of said interconnector in contact with the lateral face of the electrolyte membrane is greater than 90 degrees.
