Abstract
A new experimental technique for fast electrochemical impedance spectr oscopy (EIS), compatible with both the frequency domain and the time d omain measurement techniques, is described. It can be successfully app lied for time-resolved EIS measurements under nonstationary conditions . Impedance spectra obtained in situ during the current relaxation in a potential step experiment, using Pt electrode in Fe2+/Fe3+ redox ele ctrolyte, are presented as an application example.
