Significance The multiple types of efficient oxygen transport paths were demonstrated in high‐mechanical‐strength hepta‐bore Ba 0.5 Sr 0.5 Co 0.8 Fe 0.2 O 3‐δ hollow fiber membranes. These types of paths play a prominent role in enhancing oxygen permeation fluxes (17.6 mL min −1 cm −2 at 1223 K) which greatly transcend the performance of state‐of‐the‐art Ba 0.5 Sr 0.5 Co 0.8 Fe 0.2 O 3‐δ hollow fiber membranes, showing a good commercialization prospect . © 2017 American Institute of Chemical Engineers AIChE J , 63: 4273–4277, 2017
