Abstract
Abstract Advantages of the state variable approach in the formulation of evolution equations of complex electrochemical processes are presented. This approach allows one to deal with electrochemical dynamics according to the uniform approach of process dynamics of deterministic systems with all specificity of the systems’ evolution reduced to the mathematical properties of the governing differential equations. Recommendations are formulated as to the judicious choice of the state variables based on the conservation laws. The distinction between state variables and kinetic variables is noted. The specificity of steady-states and, particularly, of the states of equilibrium is outlined. Definitions of equivalent capacities and resistances of partial processes in linear approximation are restricted to steady-states only. Electrochemical examples are presented which can be looked at as building blocks for more complex systems obtained by combination of their evolution equations.
