PROBLEM TO BE SOLVED: To provide a composite membrane capable of enhancing reliability of a planar array fuel cell, to provide a manufacturing method of the composite membrane, and to provide a manufacturing method of the fuel cell. SOLUTION: The fuel cell 10 is equipped with the composite membrane 100 on which membrane electrode assemblies 20 are arrayed in a plane. The membrane electrode assembly 20 has: an electrolyte membrane 22; a cathode catalyst layer 24; and an anode catalyst layer 26 opposite to the cathode catalyst layer 24 via the electrolyte membrane 22. Interconnectors (conductive member) 30 are installed on the side faces of the electrolyte membrane 22 opposite to the neighboring direction of the membrane electrode assembly 20, respectively. The interconnector 30 includes a support part 31 protruded to the direction of the center part of the electrolyte membrane 22 on the cathode side of the electrolyte membrane 22. The support part 31 and the surface on the cathode side of an edge part of the electrolyte membrane 22 are brought into contact with each other, and the electrolyte membrane 22 is held by the support part 31.

PROBLEM TO BE SOLVED: To reduce the number of materials needed for manufacturing a fuel cell of the flat arrangement type.SOLUTION: A fuel cell layer 100 includes: a plurality of membrane electrode assemblies 120 disposed in a planar array arrangement; and an interconnector 130 for electrically connecting an anode catalyst layer 124 of one of adjacent membrane electrode assemblies 120 to an cathode catalyst layer 126 of the other of the adjacent membrane electrode assemblies 120. Each membrane electrode assembly 120 includes: an electrolyte membrane 122; the anode catalyst layer 124 provided on one face of the electrolyte membrane 122; the cathode catalyst layer 126 provided on the other face of the electrolyte membrane 122 in such a manner that at least part of which is disposed counter to the anode catalyst layer 124. The interconnector 130 includes at least one of a material constituting the anode catalyst layer 124 and a material constituting the cathode catalyst layer 126.
Abstract:
A method for operating a passive, air-breathing fuel cell system is described. In one embodiment, the system comprises one or more fuel cells, and a closed fuel plenum connected to a fuel supply. In some embodiments of the method, the fuel cell cathodes are exposed to ambient air, and the fuel is supplied to the anodes via the fuel plenum at a pressure greater than that of the ambient air.
