摘　　要：高温水蒸气电解制氢是解决大规模氢源问题的潜在途径之一。高温固体氧化物电解池(SOEC)可以利用各种可再生能源以及先进核能提供的热能和电能,在高温下将水蒸气高效电解为氢气和氧气。SOEC结合先进核能可以实现高达50%的热氢转化效率,已经成为近年来能源领域的一个研究热点。本文较详细介绍了SOEC的原理、分类、组成材料和特点,综述了SOEC制氢的发展现状、关键材料和核心技术,展望了SOEC在先进能源技术领域的应用前景。High temperature steam electrolysis （HTSE） has received increasingly interest in recent years, which provides a potential way for the large-scale production of hydrogen. A solid oxide electrolyzer cell （SOEC） can split H2O into Ha and O2 with high efficiency. The high-temperature heat and the electrical power can be supplied simultaneously by renewable energy sources or advanced nuclear energy. The conversion efficiency of thermal energy to hydrogen in HTSE is as high as 50%. The mechanism, classification, composition and structure of SOEC are summarized. The state of the art, the key materials and core technologies of SOEC in HTSE are reviewed and its potential application in the energy fields is proposed.
