英文摘要: A strategy for the systematic selection of perovskite-type mixed conducting membranes with high oxygen permeability, phase stability and thermo-chemical stability was developed. Several promising membrane materials were then pointed out. Some of the materials were synthesized by using standard ceramic method and complexing method, their oxygen permeability and stability were investigated and compared with several typical conducting membranes such as SrCo0.8Fe0.2O3-delta and SrCo0.5FeO3.25 etc. The results show that the new materials indeed possess the expected properties. The permeability of a typical material, Ba0.5Sr0.5Co0.8Fe0.2O3-delta membrane at 850 degreesC reaches 1.16mL[STP] . cm(-2 .) min(-1), higher than that of SrCo0.8Fe0.2O3-delta membrane under similar operation conditions, the permeation flux can keep stable more than 1000h's operation.
