Abstract

A high In-dopant level BaCeO ₃ material was used as an electrolyte for a proton-conducting solid oxide fuel cell (SOFC). Indium behaved as an ideal dopant for BaCeO ₃ , which improved both the chemical stability and sinterability for BaCeO ₃ greatly. The anode supported BaCe _0.7 In _0.3 O _3-δ (BCI30) membrane reached dense after sintering at 1100 °C, much lower than the sintering temperature for other BaCeO ₃ -based materials. Additionally, the BCI30 membrane showed adequate chemical stability against CO ₂ compared with the traditional rare earth doped BaCeO ₃ . The BCI30-based fuel cell also showed a reasonable cell performance and a good long-term stability under the operating condition. Besides, the LaSr ₃ Co _1.5 Fe _1.5 O _10-δ (LSCF) was also evaluated as a potential cathode candidate for a proton-conducting SOFC.
