Influence of compaction pressure on the impedance of Gadolinium Doped Ceria electrolytes for IT-SOFCs
Renato A. N. de Oliveira, Celeste Z. A. Aquino, Magna Monteiro Schaerer +15
Gadolinium doped ceria (GDC) is one promising oxygen-ion conducting ceramic electrolyte for intermediate-temperature solid oxide fuel cells (IT-SOFCs), due to its high ionic conduc…
Toward in-situ/operando X-ray absorption spectroscopy and electrochemical characterization of solid oxide fuel cells
Renato A. N. de Oliveira, Rafael Galiza Yoshimura, Liliana Mogni +15
The focus of the present work is the development of specialized experimental instrumentation compatible with synchrotron characterization for in-situ and operando symmetric interme…
Magnetocaloric effect of nanostructured La0.6Sr0.4CoO3
Fabiana Morales Alvarez, María Belén Vigna, Mariano Quintero +2
In this study, we investigate the magnetic and magnetocaloric properties of nanostructured La0.6Sr0.4CoO3 (LSC) samples synthesized under confinement conditions within porous templ…
Crystal structure, cobalt and iron speciation and oxygen non-stoichiometry of La0.6Sr0.4Co1-yFeyO3-d nanorods for IT-SOFC cathodes
Augusto E. Mejía Gómez, Joaquín Sacanell, Cristián Huck-Iriart +7
Single-phased La0.6Sr0.4Co1-yFeyO3-d (y = 0.2, 0.5, 0.8) nanorods exhibiting the rhombohedral perovskite-type phase were synthesized by a pore-wetting technique. We studied their c…
Temperature-programmed reduction and dispersive X-ray absorption spectroscopy studies of CeO2-based nanopowders for intermediate-temperature Solid-Oxide Fuel Cell anodes
Marina S. Bellora, Joaquín Sacanell, Cristián Huck-Iriart +3
In this work, we study the influence of the average crystallite size and dopant oxide on the reducibility of CeO2-based nanomaterials. Samples were prepared from commercial Gd2O3-,…
Nanostructured La0.5Ba0.5CoO3 as cathode for solid oxide fuel cells
Augusto E. Mejía Gómez, Diego G. Lamas, Ana Gabriela Leyva +1
A simple method has been used to synthesize nanostructured La0.5Ba0.5CoO3 (LBCO) powders, by confining chemical precursors into the pores of polycarbonate filters. The proposed met…
