摘要：
Zr0.84Y0.16O1.92 (YSZ)-La0.8Sr0.2Cr0.5Fe0.5O3-delta(LSCF) disk composite membrane is investigated under CO2/CO gradient at 800-900 degrees C. It reveals that the composite has excellent stability and appreciable oxygen permeability under the operation conditions. The oxygen permeation flux is 0.033 ml cm(-2) min(-1) for the disk membrane with a thickness of 0.5 mm at 900 degrees C. For all the samples with the thickness of 0.5, 1.0 and 1.5 mm, the oxygen permeation is controlled simultaneously by bulk oxygen diffusion and surface exchange, and the apparent activation energy decreased with the decreasing thickness. It is possibly explained as that the CO2/CO atmosphere differently affects the chemical defects of the membranes with different thicknesses. (C) 2012 Elsevier B.V. All rights reserved.
