Abstract: | In the development of the third-generation fuel cells, zirconia has dominated the solid oxide fuel cell industry over the past few decades as an outstanding electrolyte material because of its high efficiency and environmentally friendly characteristics. However, with the development of computational physics such as first principles and machine learning, new insights on original conductive mechanism are proposed. In this paper, the physical and chemical properties of zirconia are briefly described, and the latest literatures on the analysis of the electrical conductivity of zirconia from the computational physics perspectives of machine learning and first-principles are reviewed. Finally, three influencing factors of oxygen vacancy concentration, diffusion barrier and resistance of impurity phase on the electrical conductivity of zirconia are analyzed by literatures and experimental verification. |
