Abstract Oxygen-permeable hollow fiber membranes with the composition Ba0.5Sr0.5Co0.78W0.02Fe0.2O3-δ were used to demonstrate the possibility of direct AC heating for in situ high-temperature X-Ray diffraction (HT-XRD) of the hollow fiber membranes during their operation. In situ HT-XRD measurements showed that under stationary conditions of oxygen flow through the hollow fiber membrane, the surface of the membrane from the permeate side (pO2.2) is determined by the oxygen partial pressure from the feed side (pO2.1), which allows to significantly reduce the operational requirements to the material of the hollow fiber membrane.
