SOLID POLYMER FUEL CELL

PROBLEM TO BE SOLVED: To provide a solid polymer fuel cell capable of securing suitable IV characteristics in spite of comparatively low operation voltage. SOLUTION: The solid polymer fuel cell 1 has an anode catalyst electrode 4a and a cathode catalyst electrode 4b having catalyst layers 3 including metal catalysts 6 and ion-exchange resins 7 on gas diffusion layers 2 with conductivity and gas permeability, and a solid polymer electrolyte membrane 8, and the anode catalyst electrode 4a and cathode catalyst electrode 4b are arranged on respective surfaces of the solid polymer electrolyte membrane 8. The metal catalyst 9 is held on at least one surface only of connected surfaces of the solid polymer electrolyte membrane 8 with the anode catalyst electrode or the cathode catalyst electrode.
