Abstract: A fuel cell module includes an electrode membrane assembly and a pair of separators. The electrode membrane assembly includes an electrode portion and a pair of gas diffusion layers. The electrode portion includes a polymer electrolyte membrane, an anode electrode formed on a first surface of the polymer electrolyte membrane, and a cathode electrode formed on a second surface of the polymer electrolyte membrane. One of the pair of gas diffusion layers is in contact with an anode surface of the electrode portion at which the anode electrode is disposed, and the other is in contact with a cathode surface of the electrode portion at which the cathode electrode is disposed. The separators sandwich the electrode membrane assembly from respective the anode surface and the cathode surface. The electrode membrane assembly and each separator are adhered to each other by a plurality of resin portions made of a resin which at least partially contains fibers. At least a part of each gas diffusion layer is impregnated with the resin.
