abstract = {Dual-phase oxygen transport membranes are fast-growing
research interest for application in oxyfuel combustion
process. One such potential candidate is CGO-FCO (60 $wt\%$
Ce0.8Gd0.2O2−δ–40 $wt\%$ FeCo2O4) identified to provide
good oxygen permeation flux with substantial stability in
harsh atmosphere. Dense CGO-FCO membranes of 1 mm thickness
were fabricated by sintering dry pellets pressed from
powders synthesized by one-pot method (modified Pechini
process) at 1200°C for 10 h. Microstructure analysis
indicates presence of a third orthorhombic perovskite phase
in the sintered composite. It was also identified that the
spinel phase tends to form an oxygen deficient phase at the
grain boundary of spinel and CGO phases. Surface exchange
limitation of the membranes was overcome by
La0.6Sr0.4Co0.2Fe0.8O3−δ (LSCF) porous layer coating over
the composite. The oxygen permeation flux of the CGO-FCO
screen printed with a porous layer of 10 μm thick LSCF is
0.11 mL/cm2 per minute at 850°C with argon as sweep and air
as feed gas at the rates of 50 and 250 mL/min.},
