摘　　要：固体氧化物燃料电池(SOFC)能够通过氢气与氧气的电化学反应将化学能转化为电能,符合清洁低碳导向,有利于“双碳”目标的实现。减小电解质的厚度有利于降低传统SOFC的工作温度并提高其在中低温(<600℃)工作环境中的电化学性能。综述了几种典型电解质制备技术的主要工艺特点和研究进展,分析了其在电解质工业生产中的优势和局限性,指出以脉冲激光沉积和磁控溅射为代表的物理气相沉积技术更符合清洁生产的理念,更适宜工业生产。Solid oxide fuel cells(SOFCs)can convert chemical energy into electric energy through the electrochemical reaction between hydrogen and oxygen,which is in line with the clean and low carbon orientation and is conducive to the realization of dual carbon target.Reducing the thickness of the electrolytes is beneficial for lowering the operating temperature of conventional SOFCs and improving their electrochemical performances in medium and low temperatures(<600℃).The main process characteristics and research progress of several typical electrolyte preparation techniques are reviewed,and their advantages and limitations of electrolytes′industrial production are analysed.It is pointed out that physical vapor deposition represented by pulsed laser deposition and magnetron sputtering is more in line with the concept of clean production and more suitable for industrial production.
