A high temperature study on thermodynamic, thermal expansion and electrical properties of BaCe0.4Zr0.4Y0.2O3−δ proton conductor
(Elsevier Science, 2016-10)
BaCe0.4Zr0.4Y0.2O3−δ (BCZY) was synthesized by solid state reaction, calcined and sintered at 1600 °C for 12 h. Crystal structure was studied by X-ray diffraction (XRD). Morphology and porosity were determined by scanning ...
Evaluation of corrosion resistance of aluminum-based alloys in bioethanol produced in Misiones
(Elsevier, 2015-09)
Nowadays, biofuels represent a large part of renewable energies destined to substitute fossil fuels, and to reduce the negative impact on the environment. Bioethanol is obtained by alcoholic fermentation, and is used pure ...
Infiltrated La0.5Ba0.5CoO3-δ in La0.8Sr0.2Ga0.8Mg0.2O2.8 scaffolds as cathode material for IT-SOFC
(Elsevier, 2018-10)
The electrochemical response of infiltrated La0.5Ba0.5CoO3-δ (LBC) in porous La0.8Sr0.2Ga0.8Mg0.2O2.8 (LSGM) has been investigated. The thermal expansion coefficient (TEC) of the resulting electrode was measured, obtaining ...
Síntese de óxidos alternativos para células a combustível de óxido sólido de temperatura intermediária
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIA E ENGENHARIA DE MATERIAIS, 2017-01-30)
Solid oxide fuel cells are the most efficient devices ever invented for the conversion of chemical fuels directly into electrical energy. These devices still have the disadvantage of operating at relatively high temperature. ...
Desenvolvimento de eletrodo FGM a base de Ni-zircônia para célula a combustível de sólido óxido
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEM, 2007-03-01)
The search for alternatives sources to fossil fuel has stimulated the
technological development of solid oxide fuel cell. Hydrogen is the ideal fuel for
this application. However, due to technical reasons, alternatives ...
Síntese e caracterização de PSFC (Pr0,5Sr0,5Fe1-xCuxO3-δ, sendo x=0,2 e x=0,4) para aplicação como catodo de células a combustível de óxido sólido
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIA E ENGENHARIA DE MATERIAIS, 2015-06-25)
The PSFC (Pr0.5Sr0.5Fe1-xCuxO3-δ) is a new mixed oxide perovskite and has been
studied and evaluated the cathode materials for intermediate temperature solid oxide
fuel cells (IT-SOFCs), mainly due to its good compatibility ...

Structural characterization and electrochemical properties of (La,Sr)(Al,Mg)O 4−δ perovskites
(Royal Society of Chemistry, 2020-07)
LaSrAl1−xMgxO4−δ (x = 0.0?0.3) layered perovskites were synthesized by a nitrate?citrate route followed by annealing in air at 1100 °C, and studied as potential electrolyte materials in solid oxide fuel cells (SOFCs). The ...
Conducta a la corrosión electroquímica del compósito TiC/Ni-20Cr en medio salino
(Universidad Michoacana de San Nicolás de Hidalgo, 2019-07)
Nickel based materials are used at low and high temperatures in applications that require resistance to creep, fatigue and resistance to environmental degradation. Nickel base alloys can be improved in their mechanical and ...
