FUEL CELL ELECTRODE SHEET AND METHOD FOR PRODUCING SAME

摘要

This fuel cell electrode sheet (3) results from a microporous layer (3a) and a catalyst layer (3b) being integrated in a sheet shape. The electrode sheet (3) is obtained by applying an MPL ink containing a binder and a carbon material to a protective sheet (S), baking the result, applying a catalyst ink containing a catalyst to the obtained microporous sheet (3a), and drying the result. Also, an electrode joined body (1) resulting from laminating the electrode sheet (3) to both surfaces of a solid polymer electrolyte film (2) is obtained by laminating the electrode sheet (3) to the solid polymer electrolyte film (2) and peeling off the protective sheet (S).
