  • Electrolytic cell comprising an interior trough
    Patent number: 7351317
    Abstract: The invention relates to an electrolysis device for halogen gas production from an aqueous alkali halide solution in several plate-type electrolysis cells stacked and arranged side by side, with electrical contacts, each of the cells with a housing consisting of two half-shells made of electrically conductive material, said housing being equipped with devices for feeding electrolytic current and the electrolysis plant reactants and devices for discharging electrolytic current and discharging the electrolysis products, with anodic electrode, cathodic electrode and a membrane arranged therebetween, built-in components being fitted in at least one of the two half-shells and permitting a defined increase in the liquid level and thus minimizing the remaining gas volume accordingly.
    Type: Grant
    Filed: October 16, 2003
