The Electrochemical Process Engineering group studies the interaction of electrode kinetics, flow, mass transfer, and materials. Our goal is to understand and optimize electrochemical processes qualitatively and quantitatively. We conduct research in the areas of water electrolysis, electroorganic synthesis, fuel cells, and redox flow batteries.
Various experimental approaches are combined with model-based analyses to gain a deep understanding of the different electrochemical systems. However, the developtment of experimental characterization techniques not only serves the purpose of system and material investigation but is also the focus of our research. Tailor-made experimental approaches are (further) developed and adapted to different electrochemical systems.
In addition to standard electrochemical methods such as cyclic voltammetry, modern measurement methods such as impedance spectroscopy including special further developments (distribution of relaxation times (DRT) method, measurements and analyses in the non-linear range) are the focus of our investigations. In order to generate additional information and to gain a detailed overall understanding of individual processes and systems including complex structure-property relationships, the electrochemical investigations are extended by in-operando approaches. Here, material or system parameters are measured and determined using chemical and physical methods such as NMR spectroscopy or infrared spectroscopy during system operation.
