Ethanol reforming using Ba0.5Sr0.5Cu0.2Fe0.8O3−δ/Ag composites as oxygen transport membranes

► Cobalt-free OTMs, BSCF and its composites, BSCF/10-40 vol.% Ag, were fabricated. ► The oxygen permeation flux of the composites was measured. ► An Rh catalyst-coated composite was tested for producing H2 from EtOH reforming. ► The composite with catalyst shifted EtOH conversion toward production of H2. ► The Rh catalyst also increased the selectivity for H2 and decreased coke formation.
