Hollow fiber (HF) membranes composed of Ba_0.5Sr_0.5Co_0.78W_0.02Fe_0.2O_3- _δ (BSCFW2) were prepared by the phase inversion technique. The maximum measured oxygens flux through BSCFW2 HF membranes was 10.4 ml/(min∗cm²) at T=900°C and pO_2,1=0.7 atm. Study of the dependence of oxygen fluxes through BSCFW2 HF on temperature (T=800-900°C) and oxygen partial pressure on the feed side (pO_2,1=0.1-0.7 atm) was performed. It was shown that the rate-determining step of oxygen permeability is the kinetics of surface reactions with activation energy of 135±10 kJ/mol for furnace heating and 90±5 kJ/mol for current heating.
