摘要： In a polymer electrolyte fuel cell in which a cathode diffusion layer (5), a cathode electrode catalyst layer (3), a polymer electrolyte membrane (1), an anode electrode catalyst layer (2), and an anode diffusion layer (4) are laminated in this order, electron conductivity of the cathode electrode catalyst layer at a portion on the side of the cathode diffusion layer is higher than at a portion on the side of the polymer electrolyte membrane and electron conductivity of the cathode electrode catalyst layer at the portion on the side of the polymer electrolyte membrane is lower than at the portion on the side of the cathode diffusion layer, and furthermore, electron conductivity of the anode electrode catalyst layer at a portion on the side of the anode diffusion layer is higher than at a portion on the side of the polymer electrolyte membrane and electron conductivity of the anode electrode catalyst layer at the portion on the side of the polymer electrolyte membrane is lower than at the portion on the side of the anode diffusion layer.
