<P>PROBLEM TO BE SOLVED: To provide a fuel battery cell stack having a simple structure, with increase in connection resistance of a jointing portion of a cathode and an anode contained, and having a high jointing strength of the jointing portion. <P>SOLUTION: The fuel battery cell stack 10 is provided with fuel battery cells 11a, 11b, and the fuel battery cell 11a is provided with a solid polymer electrolyte membrane 12a, a cathode 13a of porous metal, and an anode 14a of porous metal. The cathode 13a and the anode 14a are respectively arranged on one face and the other face of the solid polymer electrolyte membrane 12a through a catalyst layer 15a and a catalyst layer 16a. The cathode 13a of one of fuel battery cell 11a and the anode 14b of the other fuel battery cell 11b are resistance welded with a conductive metal foil 17 interposed between these, and thereby, the fuel battery cells 11a, 11b are connected capable of flowing current. <P>COPYRIGHT: (C)2011,JPO&INPIT |
