Ba0.5Sr0.5Co0.4Fe0.6O3-δ perovskite has been used to as the binder. The bundled La0.6Sr0.4Co0.2Fe0.8O3-δ hollow fibers possess high bending strength. The bundled La0.6Sr0.4Co0.2Fe0.8O3-δ hollow fibers have high oxygen flux rates. The perovskite binder also works as the catalyst to improve the surface reactions.
