TL;DR: In this article, a parametric analysis of BSCF-Oxygen Transport Membrane was performed at 1000°C with pure oxygen as the feed and argon as the sweep.

TL;DR: In this paper, asymmetric thin-film O 3−δ (LSCF) membranes supported over a porous LSCF support were manufactured by inverse sequential tape casting and surface activation was accomplished by depositing a porous layer in order to promote oxygen evolution reaction, in the permeate membrane side.

TL;DR: In this article, the influence of membrane processing on microstructure and oxygen permeability was investigated, and the closed porosity of different processed membranes was varied between 2 and 15% with uniform grain sizes in the range of approx 10μm.

TL;DR: In this article, porous supports of the same material were developed to avoid failure due to mismatches in the thermal expansion coefficients, for the purpose of minimizing concentration polarization in the support pores, the microstructure of these support-layers was optimized.

TL;DR: In this article, fabrication-relevant properties (sinteringbehaviour, thermal and chemical expansion) of LSCF (x = 0.98−xSrxCo0.2Fe0.8O3−δ) were investigated in order to select the preferred composition for fabricating a thin-film supported membrane able to withstand the thermochemical stresses encountered during manufacturing and operation with simultaneously high oxygen permeation flux.
