Abstract

An electrolysis cell for gas-evolving electrolytic processes using at least one electrode having electrode elements arranged parallel is described; the electrode elements have a thickness of up to three times the mean bubble separation diameter and have a capillary gap with respect to one another such that a motion of the gas bubbles through the electrode is brought about substantially in the direction or in the opposite direction of the electric field between the reaction surfaces of the anode and cathode.
