<P>PROBLEM TO BE SOLVED: To provide a solid-oxide fuel cell stack improved in stability and reliability of power generation by preventing Cr poisoning by Cr that evaporates from an interconnector. <P>SOLUTION: The solid-oxide fuel cell stack 1 is formed by laminating a plurality of cells 5 each with a fuel electrode 2, an electrolyte 3 and an air electrode 4 laminated in this order and interposing the interconnector 6 formed using an alloy containing chromium, between the adjacent cells. The solid-oxide fuel cell stack 1 has a bonding layer 8 bonding at least the air electrode 4 constituting the cell 5 to the interconnector 6 using a conductive bonding material 7 containing a conductive material 7a and a bonding material 7b adsorbing chromium evaporating from the interconnector 6. <P>COPYRIGHT: (C)2010,JPO&INPIT |
