ELECTROLYSIS CELL FOR INDUSTRIAL PRODUCTION OF FLUORINE Russian patent published in 2010 - IPC C25B9/06 C25B1/24 

FIELD: chemistry.

SUBSTANCE: invention relates to the technology of producing fluorine and specifically to design of a medium temperature electrolysis cell for industrial production of fluorine from molten potassium trifluoride. The electrolysis cell has a housing, a cover, gas-distributing devices, a device for supplying hydrogen fluoride, a heat exchange system, an anode block and a cathode block with louvred walls, one of which is formed by two sets of louvred plates, which provide for gas-electrolyte emulsion containing cathode gas, a bottom-up zig-zag channel between the sets of walls. In each of the two sets of this wall, the plates lie one on top of the other, both sets lie at a distance from each other such that there is no gap between them in the vertical direction, the angle of deviation from the vertical of the plates of one set is equal on value but opposite to the sign of the angle of deviation from the vertical of plates in the other set. The plates deviate in directions opposite the anodes. Plates from one set are shifted on the vertical relative plates from the other set such that, the upper face of each plate of one set does not lie below the lower face of the nearest above-lying plate of the other set.

EFFECT: proposed electrolysis cell increases specific output of fluorine to 6,5 g/l/hour.
