摘要： A method for manufacturing a separator for a fuel cell includes: a roughening step of forming a roughened region in a surface of a separator body; and a molding step of molding a gasket on the surface of the separator body. In the molding step, the gasket is molded in an area including at least a part of the roughened region.

摘要： The purpose is to suppress positional misalignment between the diffusion layer and the frame. The manufacturing method of an electrode frame assembly for fuel cell comprises the steps of: (a) placing a frame and a diffusion layer to be stacked on each other; and (b) punching out the diffusion layer and the frame in the stacked state to form in the frame an opening in a shape matching with the punched-out diffusion layer.
