Document Type and Number:
Japanese Patent JP5432231
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a solid electrolyte fuel cell which, even when brazed in an air atmosphere using Ag brazing filler metal, exhibits high bonding strength and corrosion resistivity, and a manufacturing method therefor.SOLUTION: A solid electrolyte fuel cell 3 includes an intra-cell separator 35, which is joined to a solid electrolyte body 9 by a joining layer 37 consisting of brazing filler metal. A frame part 17 of a solid electrolyte fuel cell stack 1 is composed of a lid 29, a joining layer 45, a metal frame 41, a joining layer 47, a ceramic frame 39, a joining layer 49, an intra-cell separator 35, a joining layer 51, a metal frame 43, a joining layer 53, and an intra-cell separator 15, etc. which are laminated in that order, each member being joined together into an integral body by the joining layers 45-53 consisting of brazing filler metal. The brazing filler metal used here is an Ag brazing filler metal containing therein at least one kind of oxides of elements Ni, Co, Cr, Ti, Ce, Sr, Mn, La, Sm, and Y.
