    Abstract: In the electrode, the electrocatalytically active part consists of a nickel wire gauze which is covered at least on one side by a mixture of Raney nickel and polytetrafluoroethylene which is attached to a supporting structure which conducts electric current. The supporting structure consists of a frame (2) and a grid bounded by the latter and consisting of stays (3) or expanded metal (4).

    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.

    Abstract: A gas-diffusion cathode is to be used in the trough-like electrolysis cell with horizontally disposed electrodes which are separated from each other by a membrane. The gas-diffusion cathode (3) rests on a grating (4) with supporting legs (2). A spacer (8) is disposed between membrane (6) and gas-diffusion cathode (3).

    Abstract: A gas diffusion electrode for the reduction of oxygen, which contains a hydrophobic electro-catalyst layer, is described. One side of this layer is covered with a hydrophilic layer which is composed of at least one transition metal or an oxide or mixed oxide of transition metals and can also contain a current collector in the form of a mesh. For producing the gas diffusion electrode, a hydrophobic electro-catalyst layer can first be prepared from a pulverulent mixture which contains the electro-catalyst and a hydrophobic polymer, and at least one transition metal or an oxide or mixed oxide of transition metals can be applied in a finely divided form to one side of this layer and bonded to the hydrophobic electro-catalyst layer by the application of pressure.
