首次用两相随机格点模型模拟掺杂氧化铈-碳酸盐复合电解质,进而将随机格点模型转变为随机电阻网络模型,对掺杂氧化铈-碳酸盐复合电解质导电性能进行了模拟。考察了碳酸盐体积分数、掺杂氧化铈颗粒的粒径大小、温度对复合电解质O~(2-)电导率和H~+电导率的影响。模拟结果与钐掺杂氧化铈-碳酸盐复合电解质电导率的实验数据进行了对比。结果表明,模拟计算值与实验值具有很好的吻合性。
The two-phase random lattice model was used to simulate doped ceria-carbonate composite electrolyte for the first time, and then the random lattice model was transformed into a stochastic resistance network model to simulate the conductivity of doped ceria-carbonate composite electrolyte. The effects of carbonate volume fraction, particle size of doped ceria particles and temperature on the conductivity of O ~ (2-) and H ~ + conductivity of the composite electrolyte were investigated. The simulation results are compared with the experimental data of the conductivity of samarium-doped ceria-carbonate composite electrolyte. The results show that the simulated values are in good agreement with the experimental ones.
