| 英文摘要 | a composite membrane, which comprises of one fluorite oxide phase (ce0.8gd0.2o1.9) for oxygen ionic transport and one perovskite oxide phase (gd0.2sr0.8feo3-delta) for both oxygen ionic and electronic transport, was investigated. xrd results revealed that the two oxides are compatible and showed good oxygen permeation stability at 950 c (more than 1100 h). oxygen flux of the composite membrane was two times higher than that of the gd0.2sr0.8feo3-delta mixed conducting membrane at the same conditions. at steady state, oxygen flux of a 0.5 mm membrane was 0.80 ml/(cm(2) min) under oxygen partial pressure gradient of air/he and similar to 5.0 ml/(cm(2) min) for syngas production at 950 degrees c, respectively. after similar to 440 h operation under syngas conditions, sem analysis revealed that the syngas side of the membrane still kept dense and the edx showed the transfer of elements occurred in the depth of a few microns.
