ELECTRODE CONFIGURATION FOR GAS-FORMING ELECTROLYTIC PROCESSES IN CELLS WITH AN ION EXCHANGER MEMBRANE OR WITH A DIAPHRAGM

摘要

An electrode arrangement for gas-forming electrolytic processes in membrane cells has a flat electrode containing blade-like electrode components (2), in which neighbouring electrode components are separated by a gap (3). To improve gas dissipation from the electrode/membrane region, the blade-like electrode components have an expanded metal structure in which the apertures improve the passage of the gas. The electrode components have angled upper edges (4) to assist vertical gas dissipation. The electrode arrangement is particularly suitable as an anodically connected electrode laid directly on the ion exchange membrane, but may also be used as a cathode at a distance from the membrane.
