Abstract
Alternating current heating of microtubular oxygen-conducting membranes was studied for the first time. In this case, oxygen–electron mixed-conduction membranes simultaneously act as a heater and an oxygen separator. The efficiency of the alternative heating method was tested on microtubular Ba0.5Sr0.5Co0.78W0.02Fe0.2O3–δ membranes produced by phase inversion. Alternating current heating of microtubular membranes ensures higher membrane performance in oxygen separation at T < 900°C and noticeably decreases the starting period and the lag in varying temperature conditions.
