Abstract

The invention relates to a method which is used to produce a uniform cross-flow of an electrolyte chamber of an electrolysis cell, whereby a maximum deviation from the central flow speed is less than 1 % - 25 % which is produced by suitable constructive measures. The invention also relates to an electrolysis cell (1) comprising at least two electrolyte chambers (2, 3), wherein at least one electrode (4,5) is arranged and which respectively comprises an inlet and outlet area. The cross-flow cross-section in the inlet and/or outlet area reduces in such a manner that the pressure is reduced again.
