Characterization of oxygen transport phenomena on BSCF membranes assisted by fluid dynamic simulations including surface exchange

•A complete thermo-CFD model was built for BSFC O2-membranes including gas-exchange resistance.•The effect of membrane thickness, sweep conditions (flow, type of gas) and vacuum permeation was explored.•The gas exchange limitation was studied separately on both membrane sides.•The apparent activation energy of the permeation for different extreme scenarios was determined.
