摘要
An A and/or A′ site deficient perovskite of general formula of (A1-xA′x)1-yFeO3-δ or of general formula A1-xA′xFeO3-67, wherein A is La alone or with one or more of the rare earth metals or a rare earth metal other than Ce alone or a combination of rare earth metals and X is in the range of from 0 to about 1; A′ is Sr or Ca or mixtures thereof and Y is in the range of from about 0.01 to about 0.3; δ represents the amount of compensating oxygen loss. If either A or A′ is zero the remaining A or A′ is deficient. A fuel cell incorporating the inventive perovskite as a cathode is disclosed as well as an oxygen separation membrane. The inventive perovskite is preferably single phase.
