摘要
近年来,一种新的氧离子导体磷灰石型氧化物被发现,其结构和氧离子传输方式都不同于目前已发现的几种氧离子导体(如萤石型ZrO2、钙钛矿型氧化物等),在低温下就显示出了高离子电导率和低活化能,使固体氧化物燃料电池在低温下工作成为可能。本文就近年来国外对磷灰石型电解质材料结构和性能的研究进展进行了综述。
In recent years, a new oxygen ionic conductor-apatite-type oxide has been developed. Its structure and oxygen ion transport mechanism are different from other oxygen ionic conductors which have been investigated (e. g. , fluorite-type, perovskite-type). The apatite-type oxide ion conductors show high ionic conductivity and low activation energy at low temperature, which have potential applications as electrolytes for IT solid oxide fuel cells. In this paper, the advances in research of the apatite-type oxide are reviewed.
