During 200 h of operation at 750 °C the performance of the Ba<sub>0.5</sub>Sr<sub>0.5</sub>Co<sub>0.8</sub>Fe<sub>0.2</sub>O<sub>3-δ</sub> membrane decays by 35%, while Ba<sub>0.5</sub>Sr<sub>0.5</sub>Co<sub>0.5</sub>Fe<sub>0.125</sub>Mo<sub>0.375</sub>O<sub>3-δ</sub> shows steady-state permeation and Ba<sub>0.5</sub>Sr<sub>0.5</sub>Co<sub>0.78</sub>Fe<sub>0.195</sub>Mo<sub>0.025</sub>O<sub>3-δ</sub> slows the decay by a factor of two.
