Flame spray deposition of La0.6Sr0.4CoO3−δ thin films: Microstructural characterization, electrochemical performance and degradation

“…This is in accordance with the literature where LSC films deposited by precipitation-based techniques, such as sol-gel [47] and metalor- ganic deposition [24]. LSC thin films deposited by vacuum-based techniques such as PLD [55] or laser ablation [44] are reported to show substrate-dependent orientation.…”

“…In literature promising cathode thin films were reported for potential micro-SOFCs. More specifically, LSC thin films were deposited by vacuum-based techniques, such as pulsed laser deposition (PLD) [6,[37][38][39][40][41], radio frequency sputtering [42], laser ablation [43][44][45] and precipitation-based ones, such as metalorganic deposition (MOD) [24,46], sol-gel [47,48], ultrasonic spray pyrolysis [49] and electrostatic spray assisted vapour deposition (ESAVD) [50].…”

Effects of sintering on the mechanical and ionic properties of ceria-doped scandia stabilized zirconia ceramic

“…The ionic conductivity of ScSZ is twice that of YSZ due to similar ionic radius of Sc 3+ (0.087nm) and Zr 4+ (0.084nm) that leads to lower internal stress and lower activation energy, and hence results in lower operating temperatures for a comparable conductivity [6]. Co-doping of ScSZ with small amount of other oxides such as 1-2 mol% bismuth oxide [7][8][9], 3 mol% ytterbium oxide [10], and in particular 1 mol% ceria [11] , resulted in improved phase stability and enhanced electrical performance. More efforts in the low temperature accelerated sintering are imperative to make the electrolyte fabrication process feasible in large scale SOFC production.…”

La0.4Ce0.6O1.8–La0.8Sr0.2MnO3–8mol% yttria-stabilized zirconia composite cathode for anode-supported solid oxide fuel cells

“…Furthermore, an additional layer increases the complexity of cell structure and fabrication cost. Another method is to improve the electrochemical activity for oxygen reduction of LSM cathode by introducing some active components into LSM cathode, such as the impregnation of La 0.5 Sr 0.5 CoO 3 , LaCoO 3 or LaNi 0.6 Fe 0.4 O 3 into the LSM cathode [19] and the infiltration of cobalt into LSM-(Sc 2 O 3 ) 0.1 (Y 2 O 3 ) 0.01 (ZrO 2 ) 0.89 composite cathode [20].…”
