    摘要： Methods are provided for easily obtaining a high performance electrode without using an organic solvent for making an ink of an electrode catalyst or a surfactant for making an ink of a water repellent carbon material. The methods of manufacturing an electrode for a polymer electrolyte fuel cell comprise (a) a step of adhering a polymer electrolyte or a water repellent material to fine electrically conductive particles, and granulating the electrically conductive particles to obtain multinary granules, and (b) a step of depositing the multinary granules in layer form to obtain a catalyst layer or a water repellent layer of an electrode. Apparatus for manufacturing the electrodes, as well as polymer electrolyte fuel cells using the electrodes are also provided.

    摘要： The present invention is intended to enable efficient assembly of a fuel cell stack without causing any damage to the conductive separator. In a fuel cell including an anode, a cathode, an electrolyte membrane interposed between the anode and the cathode, and conductive separators each having manifold apertures 12 and a flow channel 16 for supplying a gas to the anode or the cathode, manifold aperture connecting portions 15 are formed at an inlet-side end and an outlet-side end of the flow channel 16, respectively. Each of the manifold aperture connecting portions 15 is recessed below the upper surface of the conductive separator 11. Cover plates are fitted and fixed to the recessed portions, respectively.
