Mechanical strength, and oxygen and electronic transport properties of SrCo0.4Fe0.6O3−δ-YSZ membranes

Three membranes including SrCo0.4Fe0.6O3−δ (SCF), 9 wt.% yttria-stabilized zirconia (YSZ) doped SrCo0.4Fe0.6O3−δ (9%YSZ-SCF), 40 wt.% YSZ doped SrCo0.4Fe0.6O3−δ (40%YSZ-SCF) were prepared. The dual-phase composite, 9%YSZ-SCF, consists of mainly perovskite type and SrZrO3. The electronic conductivity of the three composites increases in the order of 40%YSZ-SCF<9%YSZ-SCF
