abstract = {La0.58Sr0.4Co0.2Fe0.8O3-δ (LSCF), deposited on a metallic
porous support by plasma spray–physical vapor deposition
(PS–PVD) is a promising candidate for oxygen-permeation
membranes. However, after O2 permeation tests, membranes
show vertical cracks leading to leakage during the tests. In
the present work, one important feature leading to crack
formation was identified. More specifically; membrane
residual stress changes during thermal loading were found to
be related to a phase transformation in the support. In
order to improve the performance of the membranes, the
metallic support was optimized by applying an appropriate
heat treatment. The observed oxygen fluxes during permeation
tests had infinite selectivity and were amongst the highest
fluxes ever measured for LSCF membranes in the thickness
range of 30 μm, supported by LSCF porous substrates.},
