METHOD AND DEVICE FOR MANUFACTURING ELECTRODE FRAME ASSEMBLY FOR FUEL CELL

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.
