Hydrogen energy - Hydrogen production

SOEC high temperature hydrogen production technology is one of the newly developed hydrogen production technologies in recent years. Compared with traditional PEM electrolyzers and alkaline electrolyzers, SOEC has many advantages, such as high efficiency, low energy consumption, reversibility and low cost.Hydrogen production by SOEC, or solid oxide electrolysis cell, is a process that uses the ion conduction properties of an electrolyte solid oxide film to split water into hydrogen and oxygen at high temperatures. The principle is mainly based on the ionic conductivity of the solid oxide electrolyte, and the electrolytic reaction is completed in the two processes of Anode (anode) and Cathode (cathode). In the Anode process, water molecules enter the solid oxide electrolyte membrane through heat to increase the activation energy and decompose into oxygen ions and protons. Oxygen ions move to the Anode on the solid oxide electrolyte, and electrons are separated and released into the circuit to form a current. In the Cathode process, oxygen ions are electrochemically reduced to oxygen on the solid oxide electrolyte and react with protons to form hydrogen.
