Abstract

A ceria based oxide - carbonate, such as Ce-based oxide-(K0.50Na0.50)2CO3 was synthesized by a coprecipitation method as reported before. In order to investigate the coexisting effect of the solid phase and binary carbonates, the high temperature Raman spectroscopy measurements were carried out. In this paper, the detailed study shows that the observed remarkable temperature-dependent is primarily the result of softening/melting of the carbonate phase as the physical state of the carbonate phase transforms from solid, softened to molten. The possible coexistence of various charge carriers, oxide phase composition, and the oxide-carbonate interfacial area are envisaged was also studied by high temperature Raman spectroscopy. This study contributes to the understanding of the properties of nanocomposite ceria-carbonate electrolyte for low-temperature solid oxide fuel cells based on the NANOCOFC approach.
