abstract = {Asymmetric membranes provide a low ionic resistance of the
functional separation layer together with a high mechanical
stability. However, the microstructure of the porous support
in the membrane assembly affects the overall flux
significantly. This effect was studied by applying the
binary friction model (BFM) for the support together with a
modified Wagner equation for the dense membrane using
transport relevant parameters obtained from micro computed
tomography data of a tape cast Ba0.5Sr0.5Co0.8Fe0.2O3–δ
support. The influence of different pore diameters and
thicknesses of the support were compared for different feed
gases (oxygen and air) and flow configurations (3-end,
4-end, assembly orientation).The effect of the support at
large pore diameters (>35 µm) for the 3-end mode transport
process using oxygen as feed gas, was negligible. This was
not the case for the 4-end mode irrespective of the feed
gas, and for the 3-end mode using air as feed gas. This was
attributed to the binary diffusion term in the BFM. Thin
small-pored supports yield the same flux as thick
large-pored supports considering a non-linear relationship
between thickness and pore size. This can be used for the
optimization of the support's microstructure with regards to
mechanical strength and permeability.},
