Abstract

During the last 20 years, electrochemical impedance spectroscopy has become one of the most widespread tools for studying the electrochemical processes that take place on the electrode surface. Thus it is necessary for students to have a good command of the fundamentals of impedance spectroscopy, but these are sometimes difficult for students to understand. In this paper, we suggest a way to train university students in impedance spectroscopy by using numerical simulations of the impedance spectra, and how to obtain and analyze a model that can explain the simulated impedance spectrum.
