Abstract

In this electrolysis apparatus, the anode and the gas diffusion cathode are arranged to be separated from one another by means of a partition. At least one element (6) which has the form of a twin trough is located between two half-shells (1, 2) which are located at the ends and of which one carries an anode (4) and the second carries a cathode (5). This twin trough is formed by a common plate (7) and a lateral wall (8), the height of which is divided by the plate and the edges of which are provided with flanges (9, 10). The anode (4) and the cathode (5) are electrically conductively connected to the wall (8) and to struts (13) which protrude vertically from the plate on both sides. In order to form a cavity (16) between the partition (14) and the cathode (5), a sealing element is arranged between these two.
