Abstract:
    A direct oxidation fuel cell includes at least one unit cell. The at least one unit cell includes an anode, a cathode, and a hydrogen-ion conductive polymer electrolyte membrane interposed between the anode and the cathode. The anode includes: a catalyst layer in contact with the polymer electrolyte membrane; and a diffusion layer. The diffusion layer includes: a porous composite layer containing a water-repellent binding material and an electron-conductive material; a first conductive porous substrate provided on the anode-side separator side of the porous composite layer; and a second conductive porous substrate provided on the catalyst layer side of the porous composite layer.
