METHOD FOR FORMING ELECTRODE OF PEFC-TYPE FUEL CELL, AND FUEL CELL

摘要

[Problem] To manufacture a membrane electrode assembly in which an electrolyte solution and a catalyst are carried in an electrolyte membrane that is thin and deforms even in air, the membrane electrode assembly being manufactured by applying an electrode ink composed of carbon and water, or water and an alcohol-based material. [Solution] Reinforcing tape is provided on both ends of an electrode ink-coated surface of an electrolyte membrane to which a back sheet is attached, thereby forming a first electrode. Since the reinforcing tape is attached to both sides of an electrolyte membrane even if the back sheet of the electrolyte membrane is peeled off so as to form the opposite polarity, a strong suction is achieved by interposing an air-permeable substrate between a heating and adsorbing roll and the reinforcing tape, and thus the electrolyte membrane does not deform even when electrode ink is applied to form a second electrode. Also, since an adhesive can be provided, instead of the reinforcing tape, on both sides of the air-permeable substrate, and uncoated portions of both sides of the electrolyte membrane can be laminated, a more improved effect can be achieved.
