摘要

High temperature (700-900 ℃) steam electrolysis (HTSE) based on solid oxide electrolysis cells (SOECs) has been valued as an efficient and clean path for large scale hydrogen production with nearly zero carbon emissions,compared with the traditional paths of steam methane reforming or coal gasification.The main advantage of HTSE is that energy demand for electrolysis reaction of H2O at gaseous state is less than that for liquid state.
