capacitance, double layer, impedance, oscillations, bistabilityAbstract
Based on impedance spectroscopy theory, the influence has been studied of electrical double layer capacitance on appearance of periodic oscillations and bistability in a model electrochemical system with potential-dependent adsorption/desorption of electroactive species and a preceding chemical reaction in the Nernst diffusive layer atplanar electrode. It has been shown that the influence of the parameter in question is essential only in high-frequency range, that is why taking it into account does not change the position of the bifurcation points of the system.References
