- 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)
