Abstract
According to one embodiment, a catalyst layer of an electrode for a fuel cell has a proton conductive inorganic oxide containing an oxide superacid compound. The compound contains an element X (Titanium, Zirconium, Silicon, Tin, Hafnium, Germanium, Gallium, Indium, Cerium, Niobium or Aluminum) and an element Y (Tungsten, Molybdenum, Chromium, Boron or Vanadium). The catalyst layer also contains a reduction-oxidation metal catalyst or a carrier carrying a reduction-oxidation metal catalyst.
