    摘要: 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 Aluminium) 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.

    摘要: A cathode includes a diffusion layer, and a porous catalyst layer provided on the diffusion layer. The porous catalyst layer has a thickness not greater than 60 μm, a porosity of 30 to 70% and a pore diameter distribution including a peak in a range of 20 to 200 nm of a pore diameter. A volume of pores having a diameter of 20 to 200 nm is not less than 50% of a pore volume of the porous catalyst layer. The porous catalyst layer contains a supported catalyst comprising 10 to 30% by weight of a fibrous supported catalyst and 70 to 90% by weight of a granular supported catalyst. The fibrous supported catalyst includes a carbon nanofiber having a herringbone structure or a platelet structure. The granular supported catalyst includes a carbon black having 200 to 600 mL/100 g of a dibutyl phthalate (DBP) absorption value.
