Abstract: This method for manufacturing a film/catalyst assembly, which is formed by bonding a catalyst layer to an electrolyte film, comprises: a liquid addition step for adding, under an air atmosphere, a liquid to only a surface of a pre-bonding electrolyte film; and a thermocompression bonding step for bonding, by thermocompression bonding, the liquid-added electrolyte film to a catalyst layer. This manufacturing method achieves, with high productivity, in the manufacturing of a membrane-catalyst assembly formed by bonding a polyelectrolyte film to a catalyst layer, both relaxation of thermocompression bonding conditions and improved adhesion between the catalyst layer and the electrolyte film.

Abstract: A method for producing a membrane electrode assembly, in which a gas diffusion layer with a catalyst layer is bonded to an electrolyte membrane, said method comprising a liquid application step wherein a liquid is applied only to the surface of the catalyst layer before bonding in the ambient atmosphere, and a thermocompression bonding step wherein the electrolyte membrane and the gas diffusion layer with the catalyst layer to which the liquid has been applied are bonded to each other by means of thermocompression. Consequently, the present invention provides a production method that is capable of achieving a good balance between relaxation of the conditions for thermocompression bonding and improvement of the adhesion between an electrolyte membrane and a gas diffusion layer with a catalyst layer, with high productivity, during the production of a membrane electrode assembly in which a polymer electrolyte membrane and a gas diffusion layer with a catalyst layer are bonded to each other.

Abstract: The present invention addresses the problem of continuously manufacturing an assembly that includes a polymer electrolyte membrane, while minimizing the incidence of warping, electrolyte membrane wrinkling, and irregular joining. In order to overcome the aforedescribed problem, the present invention is a method for manufacturing an assembly that includes a polymer electrolyte membrane, said method comprising: a preliminary pressurization step for continuously applying pressure to a sheet to be joined, which includes a polymer electrolyte membrane (10), and a joining sheet, which includes a joining layer to be joined to at least one surface of the sheet to be joined, the sheet to be joined and the joining layer of the joining sheet being in a state of contact; and a heating pressurization step in which the sheet to be joined and the joining sheet, having passed through the preliminary pressurization step, are continuously subjected to pressurization while being heated.
