Abstract
An oxide-ion conductor has the formula Ln A Ga B1 B2 oxide, wherein Ln is at least one element selected from the group consisting of La, Ce, Pr, Nd and Sm; A is at least one element selected from the group consisting of Sr, Ca and Ba; B1 is at least one element selected from the group consisting of Mg, Al and In; B2 is at least one element selected from the group consisting of Co, Fe, Ni and Cu; x is 0.05 to 0.3; y is 0 to 0.29; z is 0.01 to 0.3; and y+z is 0.025 to 0.3. The oxide-ion conductor exhibits higher oxide-ion conductivity than stabilized zirconia, excellent heat resistance and also high ion conductivity even at low temperatures, as well as exhibiting low oxygen-partial-pressure dependence of ion conductivity.
