BaCeYbO was prepared via the sol-gel method using zirconium nitrate, ytterbium trioxide, cerium nitrate and barium acetate as raw materials. Subsequently, it reacted with the binary NaClKCl salt to obtain BaCeYbO-NaClKCl composite electrolyte. The structure, morphology, conductivity and fuel cell performance of the obtained samples were investigated. Scanning electron microscope (SEM) images showed that BaCeYbO and NaClKCl combined with each other to form a homogeneous 3-D reticulated structure. The highest power density and conductivity of BaCeYbO-NaClKCl was 393 mW·cm and 3.0 × 10 S·cm at 700 °C, respectively.
采用硝酸锆、三氧化镱、硝酸铈和醋酸钡作为原料，通过溶胶 - 凝胶法制备了BaCeYbO。随后，它与二元NaClKCl盐反应，得到BaCeYbO - NaClKCl复合电解质。对所得样品的结构、形貌、电导率和燃料电池性能进行了研究。扫描电子显微镜（SEM）图像显示，BaCeYbO与NaClKCl相互结合形成了均匀的三维网状结构。BaCeYbO - NaClKCl在700℃时的最高功率密度和电导率分别为393 mW·cm²和3.0×10⁻³ S·cm⁻¹。
