ABSTRACT: Impedance Spectroscopy has become a significant tool not only in corrosion and coatings research, but also in material science, biomedical engineering as well as fuel cell and battery research. For the latter, Electrochemical Impedance Spectroscopy (EIS) is of increasing importance for modelling and diagnosis. Special care must be taken in order to determine parameters of those nonlinear devices, since there is a difference between large and small signal impedance (J. Kowal 2009).
