Abstract

A high In-dopant level BaCeO₃ material was used as an electrolyte for a proton-conducting solid oxide fuel cell (SOFC). Indium behaved as an ideal dopant for BaCeO₃, which improved both the chemical stability and sinterability for BaCeO₃ greatly. The anode supported BaCe_0.7In_0.3O_3-δ (BCI30) membrane reached dense after sintering at 1100 °C, much lower than the sintering temperature for other BaCeO₃-based materials. Additionally, the BCI30 membrane showed adequate chemical stability against CO₂ compared with the traditional rare earth doped BaCeO₃. The BCI30-based fuel cell also showed a reasonable cell performance and a good long-term stability under the operating condition. Besides, the LaSr₃Co_1.5Fe_1.5O_10-δ (LSCF) was also evaluated as a potential cathode candidate for a proton-conducting SOFC.
