The stack was developed at the Institute of Energy Technologies (IET-4) at Forschungszentrum Jülich. The primary function of this stack is to facilitate the precise and meticulous testing of diverse components utilized in the PEM electrolysis process, employing a technical scale for accurate measurement.
