Abstract: Oxygen gas separation membranes with mixed ionic and electronic conductivity (MIEC) havefound great prospects in membrane technology for oxygen separation from gas mixtures (e.g.air) under a partial pressure gradient as the driving force. The separation of oxygen usingmembranes is more energy efficient than traditional processes such as the cryogenic Lindeprocess or pressure swing adsorption (PSA). The inverse relationship between the membranethickness and flux underscores the need for a very thin membrane. Consequently, the low mechanicalstability of free-standing thin membranes motivated the processing of asymmetricmembranes, where the thin membranes are supported by a porous structure. Asymmetricmembranes provide a low ionic resistance of the functional separation layer together with ahigh mechanical stability. However, the microstructure of the porous support in the membraneassembly affects the overall flux significantly. Therefore, a porous support that provides therequired mechanical stability needed for the dense membrane, with little or no limiting effecton the overall flux is desired [...]
