Abstract
An electrochemical reactor is provided with spaced apart anode and cathode monopolar electrodes. At least one bipolar electrode, and preferably a plurality of bipolar electrodes, are disposed between the monopolar electrodes. Each bipolar electrode has a plurality of openings therethrough occupying a suitable surface area thereof, such that gas disengagement from one side of the electrode is facilitated by passage of such gas through the openings therein to the other side of the electrodes. Such a cell is particularly useful in production of peroxide by electroreduction of oxygen. Such an arrangement allows relatively high superficial current densities to be used, as well as permitting use of gas impermeable separators (e.g. diaphragms or membranes) disposed adjacent the bipolar electrodes.
