<P>PROBLEM TO BE SOLVED: To provide a fuel sell stack and a fuel cell capable of strongly jointing a current collector member to a cell to suppress increase of resistance in current collection over an extended period of use, effectively avoiding dropping of an output. <P>SOLUTION: In a fuel cell stack 60, a plurality of solid electrolyte fuel cells 62 that comprise an interconnector 72 connected to an oxygen electrode 70 or fuel electrode 66, with the oxygen electrode 70 and the fuel electrode 66 formed on both sides of a solid electrolyte 68, are electrically connected together through a current collector member 76. The fuel cell 62 and the current collector member 76 are jointed together using a conductive jointing material 120 of conductive ceramics. The jointing strength between the fuel cell 62 and the current collector member 76 is at least 0.08 MPa. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
