Caracterización estructural y estudio de las propiedades electroquímicas de óxidos derivados del ...

The aim of this work is the synthesis, structural characterisation and study of the physical properties of oxides based on GdBaCo2O5+δ for being used as cathodes in solid oxide fuel cells (SOFCs). We have studied the effect of the substitution of different transition-metal atoms by Co in the GdBaCo2O5+δ compound. In particular, the work has focused in the study of the GdBaCo2-xFexO5+δ, GdBaCo2-xMnxO5+δ, GdBaMn2- xFexO5+δ and Gd0.5Ca0.5BaCo2-xFexO5+δ systems. The oxides have been prepared by c...
