Electrocatalytic Interface Engineering


The Electrocatalytic Interface Engineering (German: Elektrokatalytische Grenzflächenverfahrenstechnik, EGV) research department concentrates on technical interfaces of electrocatalytic devices. Examples of such technical interfaces are the catalyst layers, membranes or transport layers as well as their interfaces in e.g. fuel cells or electrolyzers. The central research question for the field of the research department is: How to get the best possible structure for the functionality of a given interfacial layer or layer system?

Research Topics

The research interests of the department span the whole electrochemical cell: From catalyst development and membrane development over manufacturing of electrodes and membrane electrode assemblies to upscaling and automatization of manufacturing processes. The department focuses on polymer electrolyte fuel cells, water electrolyzers, and the electrochemical reduction of CO2. An in-depth understanding of the systems is provided by electrochemical characterization and advanced imaging and spectroscopy.
