  • selection of appropriate testing parameters
  • impedance analyzers
  • impact of wiring and cell setup
  • correction and calibration

Evaluation of Impedance Spectra – Kramers-Kronig Test, DRT-Analysis & CNLS-Fit

  • validating impedance data quality
  • Distribution of Relaxation Times (DRT)
  • CNLS-fit

Applications I - Analysis of Materials and Interfaces

  • electrolyte conductivity – impact of humidity and temperature
  • single electrode measurements – ideal counter electrode, symmetrical cell or reference electrode
  • high resistance model electrodes
  • high performance electrodes
  • impedance of further interfaces

Applications II - Analysis Single Cells and Stacks

  • test bench design
  • humidity and liquid water
  • single cells, repeat units and stacks

Impedance Modeling and Simulation

  • electrochemical processes and their operating parameter dependencies
  • deconvolution of electrode processes
  • from AC-impedance to DC-performance
