Zusammenfassung:The bistability in a model electrochemical system with potential-dependent adsorption/desorption of electroactive species and a preceding chemical reaction in the Nernst diffusive layer at spherical, cylindrical and planar electrodes is studied based on impedance spectroscopy theory. It is shown that the range of saddle-node instability giving rise to bistability regime in the nonequilibrium system depends on the form of electrode. Its symmetry reduction is a reason for a decrease in the range of saddle-node instability, this range is the widest for a spherical electrode and it is the narrowest for a planar one.
