A La0.7Sr0.3Ga0.6Fe0.4O3-δ membrane with perovskite structure is fabricated by a conventional solid-state reaction. As the oxygen permeation flux of the La0.7Sr0.3Ga0.6Fe0.4O3-δ membrane was lower than commercial gas separation membranes, we coated a La0.6Sr0.4CoO3-δ layer to enhance the oxygen perm
