Electrochemical impedance spectroscopy: Nyquist plots for HySB at stationary potential (OCP) and optimum potential. The figure presents the complex plane (the imaginary component –Zimaginary vs. the real component Zreal of impedance) for the HySB sample made at open circuit potential (blue lines) and at optimum potential (red lines). This diagram is necessary for calculating the electrochemical parameters from table no.2.
