Electrode with catalytically active surface - for use on chlor-alkali cells having double elements which allow electrode to be changed by inverting on its support

摘要

Electrode for chlor-alkali cell has a current connection in the form of a rod or bolt to which is connected the power supply. The other end is attached to a carrier which supports two electrode plates. These each have an active surface. They are mounted in the electrolytic cell in such a way that only one plate is active at one time. When this plate becomes deactivated the support unit is uncoupled and inverted to allow the second plate to be used. For use in the Hg process for chlor-alkali prodn. The system gives a longer time between complete change of electrode by allowing an inversion first.
