CATALYST-COATED MEMBRANE ASSEMBLY MANUFACTURING METHOD AND DEVICE

In order to further suppress the occurrence of wrinkles and pinholes in a polymer electrolyte membrane, a manufacturing method for a catalyst-coated membrane assembly according to the present invention includes a preliminary drying process in which a catalyst ink coated onto one surface of the polymer electrolyte membrane is preliminary dried by heating the polymer electrolyte membrane from the side of the other surface so that swelling of the polymer electrolyte membrane is returned to its original state, and a main drying process which is carried out after the preliminary drying process by heating the polymer electrolyte membrane from the side of the one surface.
