Abstract

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.
