•A dual-phase oxygen membrane based on a segmented structure is proposed.•Oxygen flux is significantly increased in the segmented membrane.•This structure reduces the reaction between the YSZ and LSM.•The membrane exhibits stable oxygen flux in the presence of both CO2 and H2O.
In this study, a dual-phase oxygen permeable membrane based on a segmented structure of yttria stabilized zirconia (YSZ) and strontium-doped lanthanum manganite (LSM) was developed using a tape casting technique. Oxygen flux was significantly increased in the segmented membrane by a significant reduction in reactions between the YSZ and LSM. The segmented membrane also exhibited stable oxygen flux in the presence of both CO2 and H2O, as well as against thermal stress. This chemically and thermo-mechanically stable YSZ based segmented membrane is proposed for real application in oxygen production.
