Nanostructured La 0.5 Ba 0.5 CoO 3 as cathode for solid oxide fuel cells
(Elsevier, 2019-08)
A simple method has been used to synthesize nanostructured La 0.5 Ba 0.5 CoO 3 (LBCO) powders, by confining chemical precursors into the pores of polycarbonate filters. The proposed method allows us to obtain powders formed ...
Electrochemical behavior of nanostructured La0.8Sr0.2MnO3 as cathodes for solid oxide fuel cells
(Electrochemical Society Inc, 2017-05)
La0.8Sr0.2MnO3 (LSM) is one of the most commonly used cathodes in Solid Oxide Fuel Cells (SOFC). In spite of the fact that nanostructured cathodes are expected to display improved performance, the high operating temperature ...
Oxygen Reduction Mechanisms in Nanostructured La0.8Sr0.2MnO3 Cathodes for Solid Oxide Fuel Cells
(American Chemical Society, 2017-03)
In this work we outline the mechanisms contributing to the oxygen reduction reaction in nanostructured cathodes of La0.8Sr0.2MnO3 (LSM) for Solid Oxide Fuel Cells (SOFC). These cathodes, developed from LSM nanostructured ...
Performance of La0.6Sr0.4Co1−yFeyO3 (y=0.2, 0.5 and 0.8) nanostructured cathodes for intermediate-temperature solid-oxide fuel cells: Influence of microstructure and composition
(Elsevier, 2016-02)
We investigated the electrochemical properties of Co?Fe perovskites, which can be used as cathodes for intermediate-temperaturesolid-oxide fuel cells (IT-SOFCs). We studied the electrochemical properties of nanostructured ...
Nanostructured LnBaCo2O6-δ (Ln = Sm, Gd) with layered structure for intermediate temperature solid oxide fuel cell cathodes
(American Institute of Physics, 2017-04)
In this work, we present the combination of two characteristics that are beneficial for solid oxide fuel cell (SOFC) cathodic performance in one material. We developed and evaluated for the first time nanostructured layered ...

(American Institute of Physics, 2017-04)
In this work, we present the combination of two characteristics that are beneficial for solid oxide fuel cell (SOFC) cathodic performance in one material. We developed and evaluated for the first time nanostructured layered ...
Dependence on composition of electronic properties and stability of Pt-Fe/C catalysts for oxygen reduction
(Elsevier B.V., 2010-11-01)
This work presents studies of electronic characteristics and alloy stability carried out for Pt-Fe/C catalysts of different compositions (10-50% Fe, in atoms) and same particle size. The electronic properties are characterized ...
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 ...
