Various types of fractal electrode/electrolyte interfaces are investigated in the presence of an
electrode reaction, the rate of which is described by the Butler-Volmer equation in a wide
range of overpotentials. Applying scaling analysis, an interesting connection between the
Tafel current at a fractal electrode, both in the limit of high and small overpotentials on the
one hand and the admittance behaviour of the same electrode on the other, reveals itself. In
particular, from Tafel plots in the limit of high overpotentials the effective transfer coefficients …
