Abstract

It is shown that the impedance of a near-electrode layer increases with the thickness of the Nernst diffusion layer. A qualitative estimation of the phase angle of the diffusion impedance depending on the frequency at different diffusion layer thicknesses is obtained. It is shown that the diffusion is a reason for a delay in the phase of changes in the surface concentration of species with respect to the current.
