为了探查二元掺杂的CeO2基电解质的性能，采用柠檬酸-硝酸盐法制备了电解质粉体Nd0.1Sm0.1Ce0.8O1.9，对材料的致密性、电导率、输出性能等性能进行表征。结果显示，SNDC呈现单一的立方萤石相。当烧结温度升高到1350°C时，样品完全致密，电导率最大。SNDC样品的TEC平均值为13.7×10-6 K-1。单电池Ni-SNDC|SNDC|SBCO-SNDC在650°C时开路电压为0.71 V，最大功率密度为372 mW/cm2，欧姆阻抗0.3Ω·cm2。

In order to study the performance of two elements-codoped CeO2 based electrolyte, the Sm0.1Nd0.1Ce0.8O1.9 (SNDC) powder was synthesized via a citric-nitrate combustion process. The properties of the electrolyte material were characterized. The results show that the SNDC powder exhibit a single phase with a cubic fluorite structure. When the sintering temperature reaches 1350° C, the ceramic is very dense and the electrical conductivity reaches the highest. The average thermal expansion coefficient of SNDC is 13.7 ×10-6K-1. Testing the single cell Ni-SNDC|SNDC|SBCO-SNDC, the open circuit voltage of 0.71 V, maximum power density of 372 mW/cm2 and the ohmic resistance of 0.3Ω·cm2 were obtained at 650°C.
