Abstract (en)
[origin: US6503377B1] An electrolysis apparatus for producing halogen gases from aqueous alkali halide solution, having a number of plate-like electrolysis cells which are arranged beside one another in a stack and are in electrical contact and which each have a housing comprising two half-shells of electrically conductive material with external contact strips on at least one housing rear wall, and in each case having two essentially flat electrodes (anode and cathode) and the anode and cathode being provided with apertures like venetian blinds for the electrolysis starting materials and the electrolysis products to flow through, being separated from one another by a dividing wall and arranged parallel to one another and being electrically conductively connected to the respective associated rear wall of the housing by means of metal reinforcements, is intended to provide a solution with which, even at current densities above 4 kA/m2 and correspondingly increased production of gas in the boundary layer, it is possible to operate while maintaining lasting service lives of the membrane and with few pulsations.This is achieved by the venetian-blind apertures (8B, 9B) of the anode (8) and cathode (9) being arranged at an angle with respect to the horizontal.
