Abstract

In this work we present a method for the pre-identification of impedance measurements by the distribution of relaxation times (DRT). Several new features for parameter identification for electrochemical systems such as batteries and fuel cells are presented. The approach enables robust, accurate and consistent fit results for complex technically relevant systems with a large number of polarization processes involved in the impedance response.
