摘要：

High oxygen permeability was achieved using an asymmetric Ba0.95La0.05FeO3-delta membrane. In this membrane, oxygen diffuses physically through pores of a porous support and oxygen permeates electrochemically through a dense layer. The oxygen permeation flux of the asymmetric Ba0.95La0.05FeO3-delta membrane reached more than 10 cm(3) (STP) min(-1) cm(-2) from a test gas containing 50% oxygen at 930 degrees C.
