New SOFC electrode materials: The Ni-substituted LSCM-based compounds (La0.75Sr0.25)(Cr0.5Mn0.5−xNix)O3−δ and (La0.75Sr0.25)(Cr0.5−xNixMn0.5)O3−δ

A composite cathode based on scandium-doped chromate for direct high-temperature steam electrolysis in a symmetric solid oxide electrolyzer

“…1(a1) and (a2) shows XRD Rietveld refinement patterns of prepared LSCM and reduced LSCM powders, respectively. The LSCM is single phase with the perovskite structure and stable in oxidizing and reducing conditions, as reported previously in the literature [44,45]. As shown in Fig.…”

Evolution of the electrochemical interface in high-temperature fuel cells and electrolysers

“…This not only allows for such attractive structural interplay, but also for combining it with other desirable electrode functionality (see Figure 2a) 84,87,89,91,95 , chromite 86,90,94 or chromite-manganite 93,96 perovskite supports. These have been applied to solid oxide fuel cells 86,90,92,94,97 , electrolysis cells 95,98 and for other catalytic process 36,84,85 .…”

Effect of anode firing on the performance of lanthanum and nickel co-doped SrTiO3 (La0.2Sr0.8Ti0.9Ni0.1O3−δ) anode of solid oxide fuel cell

“…into a pre-sintered electrode backbone. The technique often causes problems such as inhomogeneous repartition of metallic particles, and leads to agglomeration of metallic particles and to their coarsening if an additional high-temperature thermal treatment is required during cell fabrication or cell testing [30]. The process is also inconvenient because it often requires many steps and long processing times.…”

“…In contrast, the ex-solution technique is simple, so it has advantages such as reduction of cell fabrication time and of associated costs. In addition, metal exsolutions are often accompanied by a dramatic reduction in the anode polarization resistance [30]. Ni ex-solution on (La,Sr)CrO 3 -based anodes [30], Ru ex-solution on (La,Sr)CrO 3 -based anodes [20], and Co or Cu ex-solution on CeVO 3 -based anodes [31,32] have been reported.…”
