Abstract

L'invention porte sur une cellule, un système et un procédé électrochimiques servant à convertir de l'halogénure d'hydrogène quasiment anhydre en gaz halogène quasiment sec. Le procédé de l'invention s'avère utile pour convertir de l'halogénure d'hydrogène anhydre, en particulier, du chlorure d'hydrogène, du fluorure d'hydrogène, du bromure d'hydrogène et du iodure d'hydrogène en gaz halogène, tel que du chlore, du fluor, du brome ou de l'iode. Dans cette invention, en particulier, on approvisionne en eau la membrane à transport cationique au niveau de la cathode de différentes manières. L'invention permet de récupérer un fluide libéré côté cathode et de retourner après recyclage le fluide récupéré au côté cathode de la membrane. On peut ainsi recycler le fluide récupéré qui a été libéré pour alimenter la membrane en eau, ce qui permet d'augmenter et/ou de réguler la densité de courant limite de la cellule.
