description PROBLEM TO BE SOLVED: To provide a method for joining a separator for a fuel cell and an electrode diffusion layer reducing contact resistance between the separator and the electrode diffusion layer, reducing the number of constituting members, and reducing an assembly man-hour. SOLUTION: The method for joining the separator for the fuel cell and the electrode diffusion layer is that the electrode diffusion layer on an anode side made of carbon fibers is piled on a first separator 20 made of thermoplastic resin, a pressing force is applied to the electrode diffusion layer on the anode side and the first separator 20, the electrode diffusion layer 15 on the anode side is vibrated to generate friction heat, and the electrode diffusion layer 15 on the anode side is welded to the first separator 20 with the friction heat.
