固体氧化物燃料电池电解质材料概述

Review on Electrolytes of Solid Oxide Fuel Cells

固体氧化物燃料电池(SOFC)作为燃料电池发展的第三代产物,它具有高燃料转化率、高功率密度和环境友好等优点,被誉为一种具有广阔应用前景的技术。本文从材料特性、发展状况、存在问题和研究趋势等方面概述了几种萤石结构和钙钛矿结构的SOFC电解质材料。中低温SOFC电解质材料是未来主要研究方向,如果能解决材料的制备成本、稳定性等问题,那么中低温SOFC有望实现商业化。

Solid oxide fuel cells,as the third generation fuel cell,were considered as one of the most promising technologies for their high-efficiency electric energy generation,high power density and environmental-friendly character. Several fluorite and perovskite electrolytes for SOFC were reviewed from the aspects of their characters,status of development,shortcomings and research trends. The meso-low temperature electrolyte for SOFC would be the main research field in the future. The meso-low temperature SOFC would be commercialized if the problems of high preparation cost and poor stability of the electrolyte materials were solved.
