PROBLEM TO BE SOLVED: To provide a method of obtaining a fuel cell with which high proton conductivity between an electrolyte membrane and a catalyst layer, small contact resistance between the catalyst layer and the gas diffusion substrate and good battery characteristics are realized. SOLUTION: A spliced body of an anode gas diffusion substrate 1/an anode catalyst layer 2 is made by applying and drying a paste made of a catalyst and a proton conductive polymer dispersed in a solvent on the anode gas diffusion substrate 1. And the anode gas diffusion substrate 1/anode catalyst layer 2/an anode electrolyte layer 3 are made on the surface of the anode catalyst layer 2 by applying the conductive polymer on the anode catalyst layer 2, which are subsequently spliced together with a cathode gas diffusion substrate 6/a cathode catalyst layer 5/cathode electrolyte layer 4 made in the same way, with their electrolyte layers facing each other to manufacture a spliced body of a diffusion substrate/a catalyst layer/an electrolyte membrane for a cell. |
