A bipolar electrode useful in bipolar cell stack electrochemical cells where one of the electrode surfaces is patterned with active and relatively inactive areas where the surface area ratio of the active areas of the electrode surface to the total electrode surface is between 1:2 and 1:50. The use of a grid-like pattern of electrocatalytic material over a conductive substrate is preferred. The electrodes can be used for certain redox reactions to favor particular reaction products.

Electrode configuration for gas-forming electrolytic processes in

An electrode for mercury chlor-alkali electrolytic cells includes a plurality of activated electrode elements consisting of flat sections standing on edge and having recesses on their lateral surfaces which extend from the lower edge to the upper edge of the lateral surfaces. The recesses in the lateral surfaces promote the transport of the gas bubbles produced electrolytically away from the area of the electrode gap and achieve a boundary surface as free of gas bubbles as possible between the anode and the electrolyte in the area of the electrode gap for the purpose of improving the energy efficiency.
