Abstract:
A catalyst-coated membrane that includes an anode catalyst layer, a cathode catalyst layer, and a hydrogen ion conductive polymer electrolyte membrane interposed between the anode catalyst layer and the cathode catalyst layer, a peripheral area of at least one of the anode catalyst layer and the cathode catalyst layer is provided with a decrease portion in which the mass of the electrode catalyst per unit area of the catalyst layer decreases from the inner side toward the outer side.
