During her 19 years experience, Ulrike Krewer developed a unique method repertoire for model-based and dynamic analysis of processes in electrodes and electrochemical cells. Her focus is on electrochemical microkinetics and macrokinetics as well as degradation for various fuel cells, batteries and electrosynthesis processes. Her group is one of only few groups world-wide that does indepth kinetic modelling of processes at electrodes on the macroscopic level (not molecular simulation), including complex networks of electrochemical and chemical reactions, sorption and degradation/surface changes. Her simulation of electrochemical impedance spectra, cyclovoltammograms or other electrochemical and even (surface) concentration measurements allowed her to identify reaction kinetics, elucidate limiting and dominant steps during reaction or surface change processes, and identify optimal electrode structures or compositions. Highlights in method development are the establishment of nonlinear frequency response analysis for analysis of battery state and electrode kinetics, the first differential electrochemical mass spectrometer for technical electrodes, coupled kinetic Monte-Carlocontinuum mechanic models for build-up of degradation layers.
For her research she got numerous awards; she is in the board of numerous DFG initiatives and conferences; she is elected regional representative of the International Society of Electrochemistry.
