Abstract
(DE)
Es wird eine Elektrolysezelle für gasentwickelnde elektrolytische Prozesse unter Verwendung von mindestens einer Elektrode mit parallel angeordneten Elektrodenelementen (1) beschrieben, die Elektrodenelemente einer Dicke (3) bis zum dreifachen des mittleren Blasenablösedurchmessers besitzt und die zueinander einen solchen Kapillarspalt (4) aufweisen, der eine Bewegung der Gasblasen durch die Elektrode im wesentlichen in Richtung bzw. Gegenrichtung des elektrischen Feldes zwischen den Reaktionsflächen von Anode und Kathode hervorruft.
(EN)
An electrolytic cell for electrolytic processes in which gas is evolved comprises at least one electrode with parallel electrode elements (1). The electrode elements have a thickness (3) up to three times the average diameter of a released bubble and the capillary gap (4) between the electrode elements is such that the gas bubbles move through the electrodes essentially in the direction of the electric field between the reaction surfaces of the anode and the cathode, or the opposite direction.
(FR)
La cellule électrolytique décrite comporte au moins une électrode pourvue d'éléments parallèles (1). Ces éléments présentent une épaisseur (3) atteignant trois fois le diamètre moyen d'une bulle libérée, et l'intervalle capillaire (4) entre les éléments d'électrode est tel que les bulles de gaz passent à travers les électrodes sensiblement dans le sens ou à contresens du champ électrique entre les surfaces de réaction de l'anode et de la cathode.
