PROCESS AND APPARATUS FOR THE READJUSTMENT OF THE OPERATIONAL SETTING IN AN ELECTROLYSIS CELL

摘要

1. A process for regulating the operating point position of a cell wherein is carried out an electrolysis whose current-voltage characteristic exhibits a plateau, characterized in that to an electrolysis DC voltage corresponding to a point of the plateau is superimposed an AC voltage of determined amplitude and wave form, from a possible distortion of the wave form of the cell current AC component is deduced a shift of the operating point and the DC voltage supplying the cell is corrected in order to reduce this shift and to maintain the operating point of the cell on the plateau.
