Abstract
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.
