摘要

Theoretical analysis of a model electrochemical system is performed. An equation for the critical time of the onset of a convective instability and natural convection in a plane electrolyte layer between two horizontal electrodes is derived. The cessation of damping of fluctuations of the electroactive-ion concentration is taken as the condition for the onset of a convective instability.
