摘要
可再生能源一直是人们关注的焦点。氢能是一种无污染的可再生能源,在所有的制氢方法中,只有电解水是最洁净地将可再生能源转化为电能的方法。采用固体氧化物电解池电解高温水蒸气制备氢气,具有高效、洁净、环保的特点,还可以克服传统低温电解水制氢的缺点。主要介绍了固体氧化物电解池电解高温水蒸气的工作原理、电解池结构及其关键材料,综述了近几年国内外SOEC电解水的应用研究进展,并总结了增强SOEC循环稳定性和提高产氢率所亟待解决的问题。
Renewable energy resources have attracted great interests in recent years.Hydrogen is a renewable energy source.Of all the methods of producing hydrogen,water electrolysis is probably the cleanest when it is combined with a renewable energy source to produce the electricity.Compared with the conventional low temperature water electrolysis process,which consumes a huge amount of electrical energy,high temperature steam electrolysis using solid oxide electrolysis cells （SOEC） can generate hydrogen with high efficiency.In this paper,the cell structure,material selection and working principal of SOEC for water electrolysis are introduced.The recent developments on high temperature SOEC for water electrolysis are also reviewed.The improvement on recycle stability and development of novel materials for increasing the electrolysis efficiency of SOEC are discussed as well.
