Figure 4

AC impedance (Z) measurements for Points 1, 2, 3, 6, and 7. Bode plots representing (a) real Z vs. frequency, (b) imaginary Z vs. frequency, (c) absolute Z vs. frequency, and (d) phase Z vs. frequency are shown to corroborate the Nyquist plots shown in (e) with the equivalent circuit. The frequencies used for EIS imaging are shown with dotted lines. Panel (f) shows the DRT results that can be correlated to specific electron transfer surface events in the Nyquist plots in (e).
