The fuel cell module includes a membrane-electrode assembly (MEA) including a polymer electrolyte membrane, an anode catalyst layer disposed on a surface of the membrane, a cathode catalyst layer disposed on the other surface of the membrane, and a pair of gas diffusion layers laminated on the anode catalyst layer and the cathode catalyst layer respectively, a pair of separators sandwiching the MEA; and a sealing member sealing the MEA and each of the pair of separators together. One gas diffusion layer and the sealing member overlaps in a thickness direction within a region including a center-side edge of the sealing member, and the one gas diffusion layer is notched through in the thickness direction at a part of a portion corresponding to the region.
