文摘

In this study, effect of barium chromium oxides coated Ba_0.5Sr_0.5Co_0.8Fe_0.2O_3¡À¦Ä (BSCF) membrane on oxygen permeation flux was investigated experimentally. Porous barium chromium oxide (BaCrO_x) films were deposited by the dip coating method onto BSCF membranes to improve the performance particularly in volatile chromium conditions. We conclude that oxygen permeation in BaCrO_x coated BSCF membranes is very high (2.31 mL/min cm²) under an air/helium (20 mL/min) gradient at 950 ¡ãC. This finding is in contrast with the well-known unprotected BSCF membranes.
