Síntese citrato-hidrotermal e caracterização eletroquímica de LSCF para aplicação como catodo em célula a combustível de temperatura intermediária
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia MecânicaTecnologia de Materiais; Projetos Mecânicos; Termociências, 2012-05-08)
The lanthanum strontium cobalt iron oxide (La1-xSrxCo1-yFeyO3 LSCF) is the most commonly used material for application as cathode in Solid Oxide Fuel Cells (SOFCs), mainly due to their high mixed ionic electronic ...
Uso da técnica de serigrafia para deposição de filmes de catodo de pilha a combustível de óxido sólido
(Universidade Federal de Minas GeraisUFMG, 2012-07-23)
The cobaltite ferrite of strontium-doped lanthanum (LSCF) has beendemonstrated as a highly promising material for use as fuel cell cathodes of solid oxide due to its mixed conductivity (ionic and electronic) and high ...
Study of the rate limiting steps and degradation of a GDC impregnated La0.6Sr0.4Co0.8Fe0.2O3-δ cathode
(IOP Publishing, 2017-05)
In this work, a Solid Oxide Fuel Cell (SOFC) cathode surface modification by nanoparticle impregnation was carried out. La0.6Sr0.4Co0.8Fe0.2O3-δ (LSCF) ceramic cathodes impregnated with Ce0.8Gd0.2O3-δ (GDC) nanoparticles ...
Electrophoretic Codeposition of La0.6Sr0.4Co 0.8Fe0.2O3-δ and carbon nanotubes for developing composite cathodes for intermediate temperature solid oxide fuel cells
(Wiley Blackwell Publishing, Inc, 2010-01)
Carbon nanotubes (CNTs)/La0.6Sr0.4Co 0.8Fe0.2O3-δ (LSCF) composite films have been fabricated by electrophoretic codeposition on Ce0.9Gd 0.1O1.95 (CGO) substrates. CNTs are used as a sacrificial phase to produce ordered ...
Cobalt-Iron red-ox behavior in nano-structured La0.4Sr0.6Co0.8Fe0.2O3-delta cathodes
(Elsevier Science, 2013-02)
Nano-sized La0.4Sr0.6Co0.8Fe0.2O3−δ (LSCF) perovskite samples (prepared by a conventional acetate route and a novel acetate synthesis with HMTA additives), were tested simulating a red–ox cycle. The crystallography was ...
Enhanced Oxygen Reduction Reaction Kinetics in Nanocrystalline IT-SOFC Cathodes
(The Electrochemical Society, 2013-10)
Solid oxide fuel cell performance is usually limited by high cathodic area specific resistance (ASR) at intermediate temperatures (500-700°C). ASR can be decreased by reducing particle size to nanometer range. This improvement ...
