Characterization of components for hydrogen technology

Fuel cell laboratory to test laboratory-scale single cells, fuel cell components and peripheral aggregates.

Center for Fuel Cells, Electrolysis and Synthetic Fuel

In the “Center for Fuel Cells, Electrolysis and Synthetic Fuels”, components and sub-systems for hydrogen technology are tested and characterized with scientifically based methods for applications in the fields of PEM electrolysis, PEM fuel cells (particularly for automotive applications), Power-to-Gas (PtG), Power-to-Liquid (PtL) and Power-to-Chemicals (PtC).
