<P>PROBLEM TO BE SOLVED: To provide a solid electrolyte fuel cell which is sealed sufficiently by a metal sealing material and reduced in thermal hysteresis due to brazing or the like, and has high temperature uniformity. <P>SOLUTION: The solid electrolyte fuel cell is provided with a plurality of unit cells having a solid electrolyte layer 11 (made of ZrO<SB>2</SB>based ceramic or the like), a fuel electrode 12 (made of a mixture of Ni and ZrO<SB>2</SB>based ceramic) installed on one face, and an air electrode 13 (made of a double oxide such as La<SB>0.6</SB>Sr<SB>0.4</SB>Co<SB>0.2</SB>Fe<SB>0.8</SB>O<SB>3±δ</SB>or the like) installed on the other face, a separator (made of stainless steel or the like) installed between the unit cells, and a gas seal part 2 composed of a metal sealing material (made of Ag, Au, Cu or the like or an alloy containing these or the like) installed on at least one face of this separator. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
