Abstract
Procédé d'électrolyse, notamment pour la production d'un hydroxyde de métal alcalin et de chlore par électrolyse d'une saumure de chlorure de métal alcalin. On fait passer un courant électrique depuis une anode, à travers un électrolyte aqueux, vers une cathode qui est un composé d'intercalation de carbone et de fluor. Application à l'électrolyse des saumures de chlorure de métal alcalin.
