FUEL CELL LAYER, FUEL CELL SYSTEM, AND METHOD FOR MANUFACTURING THE FUEL CELL LAYER

摘要

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.
