英文摘要	This paper reported on the fabrication of tri-layered oxygen transport membranes, "porous vertical bar dense vertical bar porous" Zr0.84Y0.16O2-delta-La0.8Sr0.2Cr0.5Fe0.5O3-delta (YSZ-LSCF), by the tape casting, tape lamination and co-firing techniques. Catalytically active nano-scale particles of LaNi0.6Fe0.4O3-delta (LNF) were impregnated into the porous scaffolds. In order to quantatively determine the resistances of the oxygen reduction or evolution reactions against oxygen permeation, an additional dense YSZ layer was introduced inside the dense YSZ-LSCF permeation layer. Electro-chemical measurements on the resulting five-layered solid oxide fuel cells showed a large reduction in the interfacial polarization resistances at the presence of these LNF catalysts, with the lowest values observed at the LNF loadings of 12wt%. In particular, the cathodic and anodic polarization resistances were 0.26 and 0.08 Omega.cm(2) at 800 degrees C, respectively. The oxygen permeation flux under the air/CH4 gradient was 7.6 mL/(cm.min), which was 14 times higher than the measured value for the blank YSZ-LSCF membrane. Further impedance analysis indicated that the charge transfer step during oxygen reduction may limit the overall oxygen permeation process.
