Nyquist diagrams for HyBS sample at 600 mV (optimum potential) (black-experimental; green-fitted). The figure presents the complex plane (the imaginary component -Zimaginary vs. the real component Zreal of impedance) for the HySB sample made at optimum potential (dotted line) and fitted results corresponding to equivalent electric circuit presented in Fig. 17 (green straight line).
