Patent ID: 8778565

Claim:
A method for making a solid oxide fuel cell interconnector, comprising sintering a material for making a solid oxide fuel cell interconnector for a period of time and at a temperature sufficient to make SrAl 12 O 19 , wherein the material for making a solid oxide fuel cell interconnector comprises (Sr x E 1-x )TiO 3 (wherein x satisfies 0.01≦x≦0.5, and E represents one or more elements selected from the group consisting of La, Pr, Nd, Sm and Gd) and Al 2 O 3 , wherein the Al 2 O 3 content relative to the (Sr x E 1-x )TiO 3 is not less than 2 mol % and not more than 10 mol % and wherein the sintering allows the following reaction: (Sr x E 1-x )TiO 3 +αAl 2 O 3 →Sr (x-α/6) E (1-x) TiO 3 +(α/6)SrAl 12 O 19 (A), wherein α indicates Al 2 O 3 content relative to the (Sr x E 1-x )TiO 3 .
