Abstract:

A cell and process is provided for the production of fluorine comprising electrolyzing a liquid mixture of fluorides of alkali metal, ammonium and hydrogen fluoride. The cell anode comprises a stock of anode plates with internal passages or it may comprise a carbon shape provided with grooves and passages and fitted to a central conductor which conducts current from the exterior of the cell to the carbon anode plates within the cell. The anode having a substantially expanded working surface has the capability of removing fluorine internally. A louvered cathode permits most of the hydrogen to be vented away from the zone between the electrodes through which current passes thus reducing the ohmic voltage loss. The cathode, rather than being louvered, can be expanded metal or punched sheet or gauze. The anode, cathode and barrier may be cylindrical in form although other shapes, for instance rectangular or square in cross section or even of hexagonal section, may be used if desired.
