(57) [Summary] [Purpose] The number of parts when stacking cell stacks can be reduced to ensure reliable setting, and mechanical strength can be increased even when the film thickness is thin. (EN) Provided is a polymer solid electrolyte fuel cell seal structure capable of eliminating gas leakage at the seal portion and improving output, and a method for producing the same. [Structure] A sealing material is integrated so as to overlap the surface of a current collector having a five-layer structure including an anode current collector, an anode catalyst layer, an ion exchange membrane, a cathode catalyst layer, and a cathode current collector. A characteristic seal structure for polymer electrolyte fuel cells. A five-layer structure composed of an anode current collector, an anode catalyst layer, an ion exchange membrane, a cathode catalyst layer, and a cathode current collector is integrated with a sealing material by using a liquid or sheet-shaped sealing material. A method for manufacturing a seal structure for a molecular electrolyte fuel cell. |
