摘要

Ba-Ce-Zr-Y (BCZY) series proton conducting materials for intermediate temperature proton ceramic fuel cell applications have been prepared using the conventional solid-phase synthesis method. BaCe0. 7Zr0. 1Y0. 1Tm0. 1O3, BaCe0. 45Zr0. 45Y0. 1O3 , and BaCe0. 2Zr0. 7Y0. 1O3 were prepared by controlling the ratio of raw materials. The effects of the sintering temperature on BCZY series materials have been evaluated by x-ray diffraction (XRD) and scanning electron microscopy (SEM). According to XRD and SEM, the perovskite structure can rapidly promote and the structure of products can be transformed from strip to block after sintering at temperatures, T ≥ 1000°C. BaCe0.7Zr0.1Y0. 1Tm0. 1O3 has better sintering properties and perovskite structure at the same temperature.
