In-Depth Analysis of Electrochemical Impedance Spectra from SOC

Attempts to elucidate the reaction mechanism occurring at the SOFC and SOEC electrodes are wide spread in literature. There is however little consent among the authors. Most literature tries to explain their data by general observations and seldom physical parameters for the various reaction processes are determined. By generating high quality data and using 3D-projection of DRT-data the first direct connection between single steps in the reaction mechanism and the electrochemical data are feasible.
