Figure 71 – Schematic diagram of (a) experimental apparatus and (b) cross section.
The overpotential η c of the cathode is dictated by the oxygen flux over the
silver electrode and is given by

Figure 72 shows the normalized cathodic polarization resistance as a function
of the oxygen partial pressure.
