Spectroscopy and imaging


In order to develop efficient electrochemical energy converters, a fundamental understanding of the underlying electrochemical processes is necessary. Using model systems, we investigate the relevant chemical reactions of electrolysis and fuel cells at the interface between the electrode and electrolyte under conditions that correspond to the planned operation. We apply vibrational spectroscopic techniques such as infrared and Raman spectroscopy in combination with atomistic simulations and imaging analysis techniques such as electron and atomic force microscopy.

Research Topics

Our basic investigations focus, for example, on materials for polymer electrolyte membrane fuel cells. The use of ionic liquids as a proton-conducting electrolyte promises to raise the operating temperature, which means a significant increase in efficiency. To further optimize these novel electrolytes, we analyze the interaction between the electrolyte, electrode, and polymer membrane.
