Abstract

Al₂O₃-CeO₂composite was prepared by coprecipitation method and used as electrolytes in semiconductor ionic fuel cells (SIFCs) . We investigated the impact of Al₂O₃-CeO₂ composite electrolyte with different molar ratio of Al₂O₃ and CeO₂ on the electrochemical performance of fuel cells. The composites were characterized by X-ray diffraction (XRD), X - ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) techniques. Among the composites, the obtained Al₂O₃-CeO₂ when the molar ratio was 1∶0.5 exhibited the best performance, and its maximum power density was 1 142 mW·cm^-2 when the open-circuit voltage was 1.099 V at 550 ℃. Furthermore, the Al₂O₃-CeO₂ cell displayed excellent mixed ionic conduction and power output performance due to the interface effect of the composite material as the fuel cell electrolyte in the test atmosphere.
