Abstract

To achieve a high oxygen permeation rate at medium and high temperature, an asymmetrically structured membrane, in which a thin dense layer (30μm) made of La 0.6Ca 0.4CoO 3-δ (LCC) and BaFe 0.975Zr 0.025O 3-δ (BFZ) was formed on a porous LCC support, was fabricated and tested for its oxygen permeability. The oxygen permeation flux significantly increased by mixing BFZ with LCC and reached a fairly high value of 1.60 cm 3 min -1 cm -2 even at 780°C.
