Improved cathode/electrolyte interface of SOFC

Synthesis and characterization of La 2 NiO 4+δ coatings deposited by reactive magnetron sputtering using plasma emission monitoring

“…In this study, we investigate the feasibility of producing thin and dense La 2 NiO 4+ δ coatings as performed in the literature [11][12][13] by reactive magnetron sputtering under unstable conditions using Plasma Emission Monitoring (PEM) [14,15]. This technique is assumed to allow the deposition of oxide coatings with high sputtering rate.…”

Electrode/Electrolyte Interphase Characterization in Solid Oxide Fuel Cells

“…Therefore, the reaction kinetics at the interphases strongly depends on chemical and structural properties of the cell components [6,[11][12][13], the electrode morphology (particle size, porosity, thickness, etc.) [14], the characteristics at the interfacial boundary [15,16] and other working parameters as the operation temperature and the gas partial pressure [17].…”

Investigation of thin perovskite layers between cathode and doped ceria used as buffer layer in solid oxide fuel cells

“…Such a layer has been prepared by dip-coating (2 μm thick) by Rieu [13] and by screen printing (5 μm thick) by Woolley [14], and it decreased polarization resistance of a La 2 NiO 4+δ electrode. Hildenbrand reported an improvement of the cathode/electrolyte interface for La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3-δ (LSCF) and La 2 NiO 4+δ cathodes using a thin dense layer obtained by pulsed laser deposition [15,16]. Recently, Dumaisnil investigated a spin-coated 700-nm-thick LSCF layer between a Ce 0.9 Gd 0.1 O 2-δ electrolyte and an LSCF cathode [17].…”
