摘要: 开发兼具高质子电导率与优异化学稳定性的电解质，是中温SOFC面临的核心挑战，BaZr0.1Ce0.7Y0.2O3−δ (BZCY)质子导体因其高质子电导率而备受关注，但其应用受限于烧结温度高、化学稳定性不足及晶界电阻大等问题。本文系统综述了BZCY电解质的改性研究进展，重点阐述了通过B位掺杂(如Ni、Cu、Dy等)调控和优化质子传导性能，分析了烧结助剂(如NiO、ZnO、Bi2O3)在促进致密化与优化微观结构方面的作用，探讨了BZCY-碳酸盐、BZCY-半导体等复合电解质中独特的界面协同传导效应，并总结了制备工艺在BZCY电解质致密化程度、微观结构均匀性及最终服役性能方面的作用。论文指出，多元协同改性是提升BZCY综合性能的关键。未来研究应致力于揭示多组分掺杂的协同机制，优化复合界面的离子传输行为，并推动高性能BZCY电解质的实际应用。
Abstract: Developing electrolytes that combine high proton conductivity with excellent chemical stability represents a core challenge for intermediate-temperature solid oxide fuel cells (IT-SOFCs). The proton conductor BaZr0.1Ce0.7Y0.2O3−δ (BZCY) has attracted significant attention due to its high proton conductivity. However, its practical application is limited by issues such as high sintering temperature, insufficient chemical stability, and high grain boundary resistance. This review systematically summarizes recent advances in the modification of BZCY electrolytes. It highlights the regulation and optimization of proton conduction performance through B-site doping (e.g., Ni, Cu, Dy), analyzes the role of sintering aids (e.g., NiO, ZnO, Bi2O3) in promoting densification and optimizing microstructure, and discusses the unique interfacial synergistic conduction effects in composite electrolytes such as BZCY-carbonate and BZCY-semiconductor systems. Furthermore, the role of interface engineering strategies, including bilayer or multilayer electrolyte structures, in improving the chemical compatibility and ion transport efficiency at the electrode/electrolyte interface is examined. The study concludes that multi-component synergistic modification is key to enhancing the overall performance of BZCY. Future research should focus on elucidating the synergistic mechanisms of multi-element doping, optimizing ion transport behavior at composite interfaces, and advancing the practical application of high-performance BZCY electrolytes.
