Electrical equivalent circuit for HyBS sample at stationary potential (OCP) used for fitting of EIS measures. This is an electric circuit consisting of a resistor (Rs)—representing the solution resistance—in series with a constant phase element (CPE1), which is in parallel with a series assembly of resistor (Rp)—representing the polarization resistance—and a second constant phase element (CPE2).
