Synthesis and characterization of La0.6Sr0.4Fe0.8Cu0.2O3-δ oxide as cathode for Intermediate Temperature Solid Oxide Fuel Cells
(Academic Press Inc Elsevier Science, 2015-05)
Nanocrystalline La0.6Sr0.4Fe0.8Cu0.2O3-δ (LSFCu) material was synthetized by combustion method using EDTA as fuel/chelating agent and NH4NO3 as combustion promoter. Structural characterization using thermodiffraction data ...
Study of the mechanisms of O2-reduction and degradation operating on La0.5-XPrxBa0.5CoO3-δ cathodes for SOFCs
(Electrochemical Society, 2017-05)
The oxygen reduction mechanism and time evolution behavior were studied for porous La0.5-xPrxBa0.5CoO3-δ (LPBC) electrodes deposited onto Ce0.9Gd0.1O1.95 electrolytes. Electrochemical impedance spectroscopy (EIS) measurements, ...
Study of BaCe0.4Zr0.4Y0.2O3-δ/BaCe0.8Pr0.2O3-δ (BCZY/BCP) bilayer membrane for Protonic Conductor Solid Oxide Fuel Cells (PC-SOFC)
(Pergamon-Elsevier Science Ltd, 2020-02)
This paper address the blocking of the electronic conductivity for a BaCe0.8Pr0.2O3-δ (BCP) material due to the addition of a BaCe0.4Zr0.4Y0.2O3-δ (BCZY) thin layer. Barium cerates (BCP and BCZY) show interesting features ...
Aluminum dual doping and oxygen transport pathway in novel Sr11Mo4−xAlxO23 oxide-ion solid electrolytes
(Elsevier Science, 2019-10)
Three new electrolytes of composition Sr11Mo4-xAlxO23-δ (x = 0.5, 1.0 and 1.5) were synthesized by wet-chemistry procedures (citrate method) as polycrystalline samples. They were crystallographically studied from synchrotron ...
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 ...
