Abstract

Selon l'invention, on utilise un dispositif d'électrolyse en sel fondu (1) comprenant un contenant interne en graphite (20) pour tenir un sel fondu (10), un contenant en graphite (30) pour contenir le contenant interne (20), et un contenant externe en acier inoxydable (40) pour contenir le contenant (30). Le contenant interne (20) est scellé hermétiquement par une plaque de protection en graphite (21), et le dispositif d'électrolyse en sel fondu (1) est également doté d'un tuyau d'alimentation en chlore (50) et d'un tuyau d'échappement (51) pénétrant à travers le contenant externe (40) et la plaque de protection (21). Une anode (60) est disposée à la partie inférieure du contenant interne (20), et une cathode (61) est immergée de façon à faire face à l'anode (60). Le contenant externe (40) est également doté d'un tuyau d'alimentation en gaz inerte (52) pour remplir l'intérieur du contenant externe d'un gaz argon.
