摘要
固体氧化物燃料电池(SOFC)是一种高效、环保的发电装置。低温化是SOFC的主要发展方向。探索适合在低温(400~600℃)条件下操作的高性能电解质材料是SOFC低温化发展的关键。近年来,研究人员发展了新型的复合电解质材料,取得了较好的成果。本文综述了近年来低温SOFC复合电解质材料的研究进展,简要介绍了复合电解质材料的特点、类型和传导机理。
Solid oxide fuel cell (SOFC) has been extensively identified as one of the most promising energy conversion technologies characterized by high efficiency and environmental friendly. Low-temperature SOFC is the main direction of development of SOFC. Exploitation of new electrolytes with excellent perfor- mance is urgently required to develop low-temperature SOFC (400 ~ 600 ℃ ). Functional composite electrolytes are regarded as the promising electrolyte materials, and the ion conductivity is significantly improved compared to single-phase materials. The recent progress in composite electrolyte, the characteristics, type and conductive mechanism of composite electrolyte were introduced in the paper.
