ABOUT PHYSICOCHEMICAL PROCESSES AT ELECTROLYTIC DECOMPOZITION OF THE WATER
Abstract
Physical processes are investigated at electrolyze waters from the power point of view at small density of a current.Reception of hydrogen is possible not only at the well-known charge of the electric power exceeding energy which can be received at burning this hydrogen (about 12 MJ/m3), but under some conditions and at the smaller charge of the electric power. The minimal density of a current (10 А/m2) is determined at which restoration of ions of gases occurs in the energy-economic way, and also value of density of a current (107А/m2) at which in a solution of electrolyte begin plasma discharges.It is experimentally shown, that if the condition of maintenance of the minimal density of a current is carried out only on one electrode also liberation of gas occurs on it as short-term transient. The kind of this gas (hydrogen or oxygen) is determined by polarity of a supplay of electrolitical cell. Values of a voltage at which gas on electrodes is not recepted are experimentally determined, is receipt on one electrode and gas starts will be receipt on both electrodes of a cell.Processes which existence it is possible to explain only passage electrons through electrolyte are revealed as well.
