SOLID OXIDE TYPE FUEL BATTERY CELL STACK

To provide a solid oxide type fuel battery cell stack which can suppress the disconnection of a conducting path between a metal member and a single cell even if the difference in linear thermal expansion coefficient difference between cell stack constituent materials is large.SOLUTION: A solid oxide type fuel battery cell stack 1 comprises: a single cell 2 having an anode 21, a solid electrolyte 22 and a cathode 23 which are laminated in this order; a metal member 3 disposed on one cell face side of the single cell 2; and an electrically conductive bonding layer 4 disposed between the single cell 2 and the metal member 3 and serving to bond the single cell 2 and the metal member 3 to each other. The bonding layer 4 comprises a material lower than the single cell 2 and the metal member 3 in melting point.SELECTED DRAWING: Figure 1 【課題】セルスタック構成材料の線熱膨張係数差が大きい場合でも、金属部材と単セルとの間の導電経路の途切れを抑制可能な固体酸化物形燃料電池セルスタックを提供する。【解決手段】固体酸化物形燃料電池セルスタック１は、アノード２１、固体電解質２２、および、カソード２３がこの順に積層された単セル２と、単セル２の一方のセル面側に配置された金属部材３と、単セル２と金属部材３との間に配置され、単セル２と金属部材３とを結合する電気伝導性の結合層４と、を有している。結合層４は、単セル２および金属部材３よりも融点が低い材料より構成されている。【選択図】図１
