Vertically arranged plate electrode for gas-forming electrolyser

In gas-forming electrolysis devices, in particular membrane electrolysers, the removal of gas presents difficulties, particularly with a close electrode spacing. However, for energy consumption reasons, a close electrode spacing is desirable. As a remedy, electrode plates to be arranged vertically in gas-forming electrolysers have already been provided with horizontally and continuously extending plate gaps and with guidance devices in the region of the gaps for removing the gases evolved. In order to avoid energy losses and to ensure rapid gas removal, in a device of the type mentioned, the entire active electrode surface of the individual electrode plate is, according to the invention, arranged parallel to, and at the shortest spacing from, the counterelectrode and the guidance device is angled at the respective upper edges of the plates of the counterelectrode.

Bipolar electrode for electrolysis cells

Bipolar electrodes arrangement for multi-cell electrolysis apparatus has a central device, formed by two elements resistant to the electrolyte and the electrolysis products, which are mutually connected parallel to each other and immovably attached to two adjacent basins in such a way that each element forms a sidewall of one of the two basins, the one element being rigid and electrically conductive and carrying anode and cathode pairs forming their electrical connection, whereas the other element by its flexibility ensures the absorption of the thermal expansion of the basin on which it is fitted.

Electrolysis cell

Electrolysis cell assembly

A compression sealable electrolysis cell that is easily and reliably manufactured, maintained and repaired comprises two insulating end pieces which can position and seal two electrode tubes with electrical contacts separated by a ceramic membrane tube where fluid can be introduced at one end piece and removed at the other end piece in the spaces between the electrode tubes and the ceramic membrane tube. The design permits the compression of the entire assembly via the fixing of nuts on one or more threaded rods extending through both end pieces without the use of an adhesive or cement and without the imposition of torque or compressive stress on the ceramic membrane tube. The water or other fluid to be electrolyzed can be introduced tangentially to spaces between the electrode tubes and the ceramic membrane tube at a angle of 0 to 15 degrees to optimize flow and contact with the electrode tubes.
