SOEC (Solid Oxide Electrolysis Cell): A device that operates at high temperatures using a ceramic membrane as an electrolyte to electrolyze water vapor and produce hydrogen. While there are other methods for hydrogen production such as alkaline water electrolysis, which uses an alkaline liquid as the electrolyte, and PEM (Proton Exchange Membrane) water electrolysis, which uses a polymer membrane as the electrolyte, the SOEC has the feature of requiring less electrical energy for electrolysis compared to these methods.
