<P>PROBLEM TO BE SOLVED: To provide an interconnector for a solid-oxide fuel cell hardly reducing or expanding at operation of the fuel, having high conductivity, without evaporation of the chromium element, and with little degradation of conductivity through changes with time; and to provide a method of manufacturing the interconnector for the solid-oxide fuel cell, the method obtaining an interconnector through which fuel electrode-side gas and air electrode-side gas hardly transmit even at a baking temperature lower than in a conventional case. <P>SOLUTION: The interconnector for the solid-oxide fuel cell is obtained by properly baking an interconnector material mainly made of niobium titanate particles expressed in a general formula: Ti<SB>(x)</SB>Nb<SB>(1-x)</SB>O<SB>2</SB>(in the formula, x is 0.90 to 0.99) and containing a zirconium compound with a content of the Zr element after the proper baking to be 0.03 to 1.0% by mass. <P>COPYRIGHT: (C)2010,JPO&INPIT |
