Abstract: An apparatus includes: an electrolyte membrane; a cathode catalyst layer provided to one main surface of the electrolyte membrane; an anode catalyst layer provided to the other main surface of the electrolyte membrane; a cathode gas diffusion layer provided on a main surface of the cathode catalyst layer not facing the electrolyte membrane; a separator including a recess through which cathode gas flows; an anode gas diffusion layer provided on a main surface of the anode catalyst layer not facing the electrolyte membrane; a voltage applicator applying a voltage between the cathode catalyst layer and the anode catalyst layer; and a fastener fastening a laminated body. The cathode gas diffusion layer is accommodated in the recess, projects from the recess in a thickness direction before fastening of the laminated body, and includes an elastic member between side surfaces of the cathode gas diffusion layer and of the recess.
