<P>PROBLEM TO BE SOLVED: To provide a solid electrolyte fuel cell in which jointing strength is high and corrosion is hardly generated even if brazing is performed using an Ag brazing material in the air atmosphere, and its manufacturing method. <P>SOLUTION: The solid electrolyte fuel battery cell 3 has an inter cell separator 35, and the inter-cell separator 35 is jointed to a solid electrolyte body 9 by a jointing layer 37 composed of a brazing material. In a frame 17 of a solid electrolyte fuel battery stack 1, a lid 29, a jointing layer 45, a metal frame 41, a jointing layer 47, a ceramic frame 39, a jointing layer 49, an inter-cell separator 35, a jointing layer 51, a metal frame 43, a jointing layer 53, and an inter-cell separator 15 or the like are laminated in this order, and these members are jointed and integrated to one another by jointing layers 45-53 formed of brazing materials. As the brazing material, the Ag brazing material containing at least one kind out of an oxide of each element of Ni, Co, Cr, Ti, Ce, Sr, Mn, La, Sm, and Y in the Ag brazing material is used. <P>COPYRIGHT: (C)2009,JPO&INPIT |
