固体氧化物燃料电池（ＳＯＦＣ）采用的是全固体的电池结构，不存在液体电解质带来的腐蚀和流失等问题，而且具有燃料适应性广等突出优点，近几年发展非常迅速，已经展示出作为集中或分散发电新技术的前景。本文较详细地介绍了固体氧化物燃料电池的特点、工作原理和关键电池材料的研制，并全面阐述了国内外发展现状和发展趋势。
Solid oxide fuel cells (SOFCs) employ an all-solid battery structure that does not suffer from problems such as corrosion and run-off caused by liquid electrolytes and has the outstanding advantages of having a wide range of fuel adaptability and has been developed very rapidly in recent years Prospects for a new technology for centralized or decentralized power generation. In this paper, the characteristics, working principle and development of key battery materials of solid oxide fuel cell are introduced in detail, and the development status and development trend both at home and abroad are expounded in a comprehensive way.
