Abstract
In this fuel cell, a cathode-side porous film that covers a cathode electrode is interposed between the cathode electrode and an air supply layer, the cathode electrode constituting electrolyte film/electrode structures. In addition, breathing holes are formed in the cathode-side porous film, and the air flowing through air supply passages passes through the breathing holes and is supplied to the cathode electrode.
