      abstract     = {Asymmetric membranes of mixed ionic-electronic conducting
                      perovskite-type oxides SrTi1-xFexO3-δ (STF, x = 0.3, 0.5
                      and 0.7) were prepared by inverse sequential tape-casting.
                      Both porous support (~600 μm) and functional membrane layer
                      (~20 μm) for a given membrane assembly were made from the
                      same composition to ensure thermochemical compatibility
                      between the layers. Oxygen fluxes were assessed in the range
                      650 -1020 °C, using either (non-pressurized) ambient air or
                      pure oxygen as feed gas at the support side of the
                      asymmetric membrane and argon as sweep gas. Notably, similar
                      oxygen fluxes (~1.2 × 10−6 mol cm−2 s−1) are measured
                      through the membranes of different compositions above 950
                      °C when using ambient air as feed gas. This observation is
                      interpreted to reflect the major role of the support layer
                      resistance in rate-limiting the oxygen fluxes through the
                      STF asymmetric membranes, which conclusion is supported by
                      comparison of the oxygen fluxes with those measured
                      previously through asymmetric membranes of
                      Ba0.5Sr0.5Co0.8Fe0.2O3-δ (BSCF) and
                      La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF). A simple
                      diffusion-convection model is used to account for the
                      observed gas phase polarization in the porous support layers
                      limiting the oxygen fluxes.},
