Oxygen permeation through tape-cast asymmetric all-La0.6Sr0.4Co0.2Fe0.8O3−δ membranes

A 30 µm dense LSCF membrane has been deposited on a porous support by means of inverse sequential tape casting, this has permitted the achievement of an O2 flux of 11.87 ml min−1 cm−2 at 1000 °C. Furthermore, the application of an activation layer allowed improving the permeation process, especially at low temperatures, obtaining an improvement of ca. 300% at 600 °C with respect to the bare membrane. 252
