PROBLEM TO BE SOLVED: To enable reduction of the manufacturing cost of a reinforcement type electrolyte film.SOLUTION: A method of manufacturing a reinforcement type electrolyte film used for a solid polymer type fuel battery comprises a step of attaching electrolyte polymer onto a sheet, and attaching a porous reinforcing film having a larger specific gravity than the band-shaped electrolyte polymer onto the electrolyte polymer to prepare an intermediate body, and a step of arranging the intermediate body so that the reinforcing film, the electrolyte polymer and the sheet are successively arranged from the rotational center in this order, and rotating the intermediate body while heating the intermediate body. In the rotating step, the center position in the film thickness direction of the reinforcing film is moved to the center position in the film thickness direction of the electrolyte polymer.SELECTED DRAWING: Figure 5 |
