Abstract A SrCe0.6Zr0.3Lu0.1O3-α electrolyte was synthesized via a citric-nitrate auto-combustion (CNA) method using Sr(NO3)2, Zr(NO3)4·5H2O, (NH4)2Ce(NO3)6, Lu2O3, HNO3 and citric acid as raw materials. Subsequently, it reacted with the molten carbonate salt to obtain the SrCe0.6Zr0.3Lu0.1O3-α-Li2CO3-Na2CO3 composite electrolyte. The morphology, structure, conductivity and fuel cell performance of the obtained samples were investigated. SrCe0.6Zr0.3Lu0.1O3-α is fully dense after calcinated at 1540 °C for 5 h SrCe0.6Zr0.3Lu0.1O3-α and Li2CO3-Na2CO3 combined with each other to form a homogeneous interconnected structure. The highest power density and conductivity of SrCe0.6Zr0.3Lu0.1O3-α-Li2CO3-Na2CO3 are 255 mW cm−2 and 8.6 × 10−2 S cm−1 at 600 °C, respectively.

摘要 采用 Sr(NO3)2、Zr(NO3)4·5H2O、(NH4)2Ce(NO3)6、柠檬酸-硝酸盐自燃 (CNA) 法合成了 SrCe0.6Zr0.3Lu0.1O3-α 电解液，以Lu2O3、HNO3和柠檬酸为原料。随后与熔融碳酸盐反应得到SrCe0.6Zr0.3Lu0.1O3-α-Li2CO3-Na2CO3复合电解质。对所得样品的形貌、结构、电导率和燃料电池性能进行了研究。SrCe0.6Zr0.3Lu0.1O3-α 在 1540 °C 煅烧 5 h 后完全致密 SrCe0.6Zr0.3Lu0.1O3-α 和 Li2CO3-Na2CO3 相互结合形成均质的互连结构。SrCe0.6Zr0.3Lu0.1O3-α-Li2CO3-Na2CO3 的最高功率密度和电导率在 600 °C 时分别为 255 mW cm-2 和 8.6 × 10-2 S cm-1。
