<P>PROBLEM TO BE SOLVED: To add inclination to an electronic conductivity and proton conductivity in an electrode layer, and provide a solid polymer fuel cell of which the power generation performance is improved. <P>SOLUTION: This is the solid polymer fuel cell in which a cathode diffusion layer 5, a cathode electrode catalyst layer 3, a polymer electrolyte film 1, an anode electrode catalyst layer 2, and an anode diffusion layer 4 are sequentially laminated. The electronic conductivity in the cathode electrode catalyst layer 3 is formed to be higher at the cathode diffusion layer side than at the polymer electrolyte film side, and lower at the polymer electrolyte film side than at the cathode diffusion side, and the electronic conductivity in the anode electrode catalyst layer 2 is formed to be higher at the anode diffusion layer side than that at the high polymer electrolyte film side, and lower at the high polymer electrolyte film side than that at the anode diffusion layer side. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
