| 摘要: 采用溶胶凝胶法制备BiVO4（BV）和Nd0.2Ce0.8O1.9（NDC）粉末，研究BV的加入对NDC电解质结构、形貌及电性能的影响。实验结果表明，NDC-5BV电解质的微观结构更致密，700℃时总电导率（σt）提高至3.35×10-2 S·cm-1，极化电阻（Rp）降低34%以上。单电池在700℃时的最大功率密度（MPD）为514 mW·cm-2，开路电压（OCV）在70 h内可以保持良好的长期稳定性。 | |

| Abstract: Sol-gel method was applied to prepare BiVO4 (BV) and Nd0.2Ce0.8O1.9 (NDC) powders. The effects of BV doping on microstructure, morphology and electrical properties of NDC electrolyte were studied. The results of experiments revealed that Nd0.2Ce0.8O1.9 electrolyte showed a highly dense microstructure. At 700℃, the total conductivity (σt) of NDC-5BV electrolyte was 3.35×10-2 S·cm-1. The polarization resistance (Rp) was reduced by more than 34% at 700℃. The maximum power density (MPD) of the single cell reached up to 514 mW·cm-2 at 700℃. During the operation time for 70 h, the open circuit voltage (OCV) can be maintained good stability. | |
