Electrolysis Cells

An electrolysis cell uses electricity to split water molecules (H2O) into hydrogen (H2) and oxygen (O2). In this way electrical energy is transformed into chemically bound energy in the hydrogen molecules. This is the reverse of the process that occurs in a fuel cell.

Electrolysis cells can be used for the production of hydrogen using surplus power from, e.g., wind turbines. Our research focus on two main development tracks: Low temperature electrolysis for operation below 300-400 °C and SOEC (solid oxide electrolysis cell) for operation above approx. 800 °C. Solid oxide electrolysis cells can also split CO2 into CO which can be used for the production of synthetic fuels.
