Iron-based perovskite cathodes for solid oxide fuel cells |
摘要 |
An A and/or A' site deficient perovskite of general formula of (A<SUB>1-x</SUB>A'<SUB>x</SUB>)<SUB>1-y</SUB>FeO<SUB>3-delta</SUB> or of general formula A<SUB>1-x</SUB>A'<SUB>x</SUB>FeO<SUB>3-67</SUB>, 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; delta 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.
