Turash M. Temporary and Spatial Selforganization in Electrochemical Systems

The dymanic model of electrocatalytic reduction of metals is suggested. In this model for account of heterogeneous processes on the elctrode, the surface parts covered with adsorbed catalyst and also with its complex with a reduced metal ion are considered as replaced systems. The resistance diagram is constructed. The form and the amplitude of oscillation in relation to the distance of the critical point are determined. The conditions of advent of spatial dissipative structures in electrochemical systems are obtained, which display the Marangoni effect. The influence of the Gragoff number on the form of convectional flows, concentrational profiles and the Nusselt number near the anode's surface have been investigated.
