PROBLEM TO BE SOLVED: To directly form a uniform catalyst layer n an electrolyte film to permit high output by forming the catalyst layer containing a catalyst and an electrolyte, on one surface or both surfaces of the electrolyte film containing alcohol with a specific number of carbon or less. SOLUTION: An alcohol treatment for dipping an electrolyte film in alcohols to include alcohols is applied. The alcohols are to have the carbon number of four or less. The electrolyte film 1 subjected to the alcohol treatment is disposed on a plate 2, and excess water and alcohol existing between the plate 2 and the electrolyte film 1 subjected to a alcohol treatment are squeezed out using a squeegee blade or the like to bring the electrolyte film 1 subjected to alcohol treatment, into close contact with the plate 2. A frame-like sheet 3 with an opening is disposed at the electrolyte film 1 subjected to alcohol treatment, and the frame-like sheet 3 is brought into close contact with the electrolyte film 1. Catalyst-dispersed material is applied to the electrolyte film 1 in the fixed state from the opening, and dried to form a catalyst layer- electrolyte joint body. |
