Abstract

The product capacity of an ion exchange membrane cell for the generation of chlorine and alkali caustic solutions is limited by mechanical design facts. A cell according to this invention allows a substantial increase of its product rates by assembling of several individual electrode plates (4A, 4B) in each single cell element, which are placed piece by piece in the halfshells of the cells, aligned, adjusted and fastened by adjustment members (16) piece by piece. Dependent on the capacity the cell elements can be equipped with different numbers of inlet and outlet pipes. With respect on the recoating procedures of the electrode surfaces outside of the cells the fastening means (16) of the electrode plates are removable in such a manner that the plates can be replaced multiple times without mechanical destruction of cell or plate parts.
