Abstract
We investigate how the changes on the electrode surface may influence the behavior of the constant–phase elements (CPE) and, consequently, electrical response of an electrolytic cell. This analysis is performed by using an experiment with Milli-Q water and stainless steel electrodes with three different types of polishment: smooth, fine sandpaper, and rough sandpaper. The experimental data is obtained from an Electrical Impedance Spectroscopy (EIS) measure and analyzed by means of an equivalent circuit with CPE elements.
