Abstract

L'invention concerne les cellules d'électrolyse à diaphragme. Elle se rapporte à un procédé de réduction de la surtension cathodique d'une telle cellule d'électrolyse qui comprend une chambre cathodique, une solution de catholyte et une cathode propre, par introduction d'ions d'un métal à faible surtension dans la solution de catholyte et par dépôt de ces ions métalliques, sous forme d'un metal, sur la cathode, au cours d'une opération in situ. Application à l'électrolyse des halogénures alcalins.The invention relates to diaphragm electrolysis cells. It relates to a method of reducing the cathodic overvoltage of such an electrolysis cell which comprises a cathode chamber, a catholyte solution and a clean cathode, by introducing ions of a metal at low overvoltage into the solution. of catholyte and by depositing these metal ions, in the form of a metal, on the cathode, during an in situ operation. Application to the electrolysis of alkali metal halides.
