Structural and electrochemical studies of Ba0.6Sr0.4Co1−yTiyO3−δ as a new cathode material for IT-SOFCs

Characterization of La0.5Sr0.5Co0.5Ti0.5O3−δ as symmetrical electrode material for intermediate-temperature solid-oxide fuel cells

“…The replacement of Co by the electronically stable Ti 4þ ions decreases the TEC and improves the chemical stability on CeO 2 -based electrolyte materials, as it has been previously reported by H. Zhao et al [25] in Ba 0.6 Sr 0.4 Co 1Ày Ti y O 3Àd oxides.…”

Zirconium stabilized Ba0.5Sr0.5(Co0.8−xZrx)Fe0.2O3−α perovskite hollow fibre membranes for oxygen separation

“…As the Zr-doping content is increased to 0.3, the lattice parameter (a) of the perovskite increases to 0.3991 nm. Furthermore, the substitution of larger Zr 4+ for Co cations also causes the shift of the perovskite peaks of the composite to the lower angle direction [7,31]. As can be …”

SYNTHESIS OF LAxSR1-xTIO3 ANODE MATERIALS BY SOL-GEL AUTO-COMBUSTION METHOD

“…Doped SrTiO 3 have the electronic-ion mix conduction characteristic under the reducing atmosphere. Fig.…”

“…However, SOFCs still have many problems related to its longevity or long term stability due to its high operation temperature, and the majority of current researches is concentrated on the development of intermediate temperature SOFCs (IT-SOFCs) [2,3]. Recently, there are intensive studies on the anode of solid oxide fuel cells, and Ni-cermet composites are the most commonly used materials as anodes for IT-SOFCs [4][5][6].…”
