A fuel cell stack includes two or more cells. The cell includes a solid polymer electrolyte membrane, a porous metallic cathode, and a porous metallic anode. The cathode is arranged on one surface of the solid polymer electrolyte membrane through a catalyst layer. The anode is arranged on the other surface of the solid polymer electrolyte membrane through a catalyst layer. Two or more cells are connected in an electrically conductive manner by resistance welding of the cathode of one of the cells and the anode of the other one of the cells with a conductive metallic foil interposed therebetween.
