One approach to lower the cost of solid oxide fuel cells (SOFCs) is operating temperatures below 1073 K allow use robust and comparatively inexpensive stainless steels not only for interconnects but also SOFC support structures. The metal supports must be sufficiently porous facilitate gas flow toward reactive sites in electrodes. Gas electrical conductivity remain adequate during any oxidation that occurs operation. In order identify microstructures most suitable as supports, a series...
Two techniques of spray pyrolysis, namely, electrostatic and pneumatic deposition, were used to deposit samaria-doped ceria (SDC) electrolyte lanthanum strontium cobalt ferrite (LSCF) cathode on cermet or metal supported anodes for solid oxide fuel cells (SOFCs) operated at reduced temperature. The deposition processes, the properties deposited films, electrochemical performances fabricated are reported in this paper. SDC electrolytes dense gas-tight, had good adhesion underlying anodes....
Metal-supported solid oxide fuel cells (SOFCs) offer many advantages, including increased robustness, improved thermal shock resistance, and decreased cost. However, fabricating metal-supported SOFCs using conventional techniques is both very difficult costly. In this study, two processes of spray pyrolysis deposition, pneumatic deposition electrostatic were used to deposit samaria-doped ceria (SDC) electrolytes on different substrates NiO–SDC anodes porous stainless steel substrates. A...
Rapid performance degradations of solid oxide fuel cells were observed when the chromium-forming metallic alloys used as interconnects. The formation strontium chromium (SrCrO4) on surface Sr-doped perovskite cathode was believed to be one main causes for cell degradation. This chromium-poisoning effect not mitigated operating temperature lowered 600°C. SrCrO4 that formed mainly found in both La0.6Sr0.4Co0.2Fe0.8O3−δ (LSCF) and Sm0.5Sr0.5CoO3 (SSCo) cathode, suggesting all...
