ABSTRACT:

Electrochemical behavior of a cell with a boundary of blocking electrode/solid electrolyte or ionic melt has been studied in galvanogarmonic mode of charge.  The possibility of application of simple and more graphic calculation technique and separation of electrochemical impedance schemes into active and reactive constituents has been found. The Jacobsen – West diffusion model as an equivalent electric circuit  valid for relatively large times or small ac frequencies has been applied. The plotting of dependences of active and reactive impedance components on ac frequency has been  used in order to find the values of parameters for studied equivalent electric circuits.
