A fuel cell includes membrane electrode assemblies disposed in a planar arrangement. Each membrane electrode assembly includes an electrolyte membrane, an anode catalyst layer, and a cathode catalyst layer disposed counter to the cathode catalyst via the electrolyte membrane. Interconnectors (conductive members) are provided on the lateral faces of the electrolyte membranes disposed counter to each another in the neighboring direction of the membrane electrode assemblies. Each interconnector includes a support portion protruding toward the central region of the electrolyte member on the cathode side of the electrolyte membrane. The support portion is in contact with the cathode-side surface of an edge of the electrolyte membrane, and the electrolyte membrane is held by the support portion.
