Electrolytic Hydrogen Production

SOEC in Operation: Stack and Steam Generator

17-kW SOEC Module

Electrolysis of water produces high purity hydrogen directly, with no need for additional clean up. High temperature steam electrolysis, where a portion of the required energy can be supplied as thermal energy, is more efficient than low temperature water electrolysis.

A high temperature electrolysis system will produce about 40% more hydrogen from a given energy input than a conventional water electrolysis system.

High temperature solid oxide fuel cells can be operated in a reverse mode to electrolyze steam to generate hydrogen.

With two decades of fuel cell experience, Ceramatec has worked on high temperature Solid Oxide Electrolysis Cells (SOEC) since 2003. A 4-kW steam electrolyzer stack module was operated for more than 2000 hours, and a 17-kW steam electrolyzer was demonstrated at the Idaho National Laboratory using stacks fabricated at Ceramatec.
