- Therefore, the effect of powders morphology on sintering temperatures and on sintered material composition, structure and conductivity has been investigated. On the considered solid solutions, an extensive structural and morphological investigation by means of X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) has been performed. The study of the conductivity performance in protonic conditions was performed by means of Electrochemical Impedance Spectroscopy (EIS) technique. The chemical stability in CO2 atmosphere has been investigated by thermogravimetric analyses. (literal)

- Solid oxide fuel cells (SOFCs) have gained much attention as promising energy conversion systems, due to their high thermodynamic efficiency and low impact to the environment. Nevertheless, the lowering of SOFCs working temperatures by means of new electrolyte materials is a key factor for their commercialization. In view of this, proton conducting electrolyte materials are promising candidates for the development of intermediate temperatures SOFCs (IT-SOFCs). Among them, various doped barium cerate compounds, such as BaCe1-xYxO3-ä, showed high proton conductivity. As a drawback, cerates are chemically unstable in the presence of CO2- containing atmospheres, such as in case of hydrocarbon fuelled SOFCs. Conversely, doped barium zirconates exhibited high chemical stability but lower proton conductivity. (literal)
