摘要：

The current, potential characteristic for Volmer-Heyrovsky reaction is multisteady-state for interaction parameter values lower than a critical value, leading to a hysteresis loop during steady-state investigation. By stimulating impedance measurements it is shown that branch switching phenomena and 2- and 3-part impedance diagrams can be observed during impedance measurements when the sinusoidal potential perturbation spans the bifurcation potentials.
