    摘要： In a polymer electrolyte fuel cell including a hydrogen ion conductive polymer electrolyte membrane; a pair of electrodes composed of catalyst layers sandwiching the hydrogen ion conductive polymer electrolyte membrane between them and gas diffusion layers in contact with the catalyst layers; a conductive separator plate having a gas flow channel for supplying a fuel gas to one of the electrodes; and a conductive separator plate having a gas flow channel for supplying an oxidant gas to the other electrode, in order to bring a hydrogen ion conductive polymer electrolyte and a catalyst metal of the catalyst layers containing the hydrogen ion conductive polymer electrolyte and conductive carbon particles carrying the catalyst metal sufficiently and uniformly into contact with each other, the polymer electrolyte is provided in pores of an agglomerate structure of the conductive carbon particles. Consequently, the reaction area inside the electrodes is increased, and higher performance is exhibited.

    摘要： A polymer electrolyte fuel cell comprising an anode, a cathode, a polymer electrolyte membrane interposed between the anode and the cathode, an anode-side separator plate having a gas flow path to supply fuel gas to the anode and a cathode-side separator plate having a gas flow path to supply oxidant gas to the cathode. Each of the anode and the cathode comprises a catalyst layer in contact with the polymer electrolyte membrane, an electrode supporting material having gas permeability and electronic conductivity, and a water repellent layer interposed between the catalyst layer and the electrode supporting material. The water repellent layer has through holes through which the catalyst layer and the electrode supporting material are electrically connected.
