Mixed‐ion and electron‐conducting perovskite membranes are used to produce oxygen‐enriched air (see picture). These membranes are thermally and mechanically stable at high temperatures (>875 °C) over a long period of time, thus making them suitable for industrial processes. Oxygen concentrations of the enriched air typically reach 30–50 vol %.
