Abstract
PROCEDE D'ELECTROLYSE D'UN CHLORURE DE METAL ALCALIN. ON UTILISE UNE MEMBRANE HOMOGENE D'ECHANGE DE CATIONS DONT L'UNE AU MOINS DES FACES EST RENDUE RUGUEUSE. LA MEMBRANE EST MONTEE DANS UNE CELLULE D'ELECTROLYSE EN FAISANT EN SORTE QUE LA FACE RENDUE RUGUEUSE SOIT TOURNEE VERS LE COTE CATHODIQUE DE LA CELLULE. CELA PERMET DE DIMINUER LA TENSION D'ELECTROLYSE POUR UN MEME RENDEMENT EN COURANT. FABRICATION DE LA SOUDE.
