- Abstract
- Proton conducting electrolyte materials are promising candidates for the development of low temperature solid oxide fuel cells. Among them, various doped barium cerate compounds, such as BaCe1-xYxO3-´, have been intensively investigated because of their high proton conductivity. As a drawback, cerates are chemically unstable in CO2-containing atmospheres, such as in case of hydrocarbon or syngas fuelled fuel cells. Conversely, doped barium zirconates electrolyte materials exhibit high chemical
stability but lower proton conductivity. A goal of this work was to obtain full-density proton conducting materials having both high conductivity and good chemical stability. In particular, the compositions investigated in this work were BaCe1-x-yZrxYyO3-´ (x=0, 0.1, 0.2, 0.3, 0.4; y=0.15, 0.20). The partial substitution of Ce by Zr in doped barium cerate considerably increased their chemical stability in CO2 atmosphere without sensibly affecting the conductivity. (literal)
