Abstract: A membrane-electrode assembly producing apparatus and membrane-electrode assembly producing method are provided which can increase the bonding strength between a polymer electrolyte film and a catalyst layer and which can produce a high-quality membrane-electrode assembly without a formation of wrinkle through a hot roll technique. An apparatus includes pre-heating unit for pre-heating a catalyst-layer supporting base material 12 that supports the catalyst layer on a surface of a transfer base material, and the polymer electrolyte film 10, thermal pressure bonding unit for heating and pressing the catalyst-layer supporting base material 12 and the polymer electrolyte film 10 to form an integrated joined member 14, and peeling unit for peeling the transfer base material 16 from the joined member 14.

Abstract: There is a manufacturing apparatus for an electrolyte membrane with gaskets by laminating an electrolyte membrane having a predetermined region on which a catalyst layer is formed and a gasket formed with an opening shaped to match the shape of the region of the catalyst layer. The manufacturing apparatus for an electrolyte membrane with gaskets includes a laminating roller that abuts on the gasket to laminate the electrolyte membrane and the gasket. The laminating roller has a surface on which a protrusion is formed. The protrusion is shaped to fit in the opening of the gasket. The manufacturing apparatus for an electrolyte membrane with gaskets includes a roller controller that operates the laminating roller such that the electrolyte membrane and the gasket are laminated while the protrusion is fitted in the opening of the gasket.
