Abstract

Elément et unité cathodiques. Ils comprennent un doigt cathodique creux avec des ailettes se prolongeant vers l'extérieur de celui-ci. Un séparateur synthétique entoure la cathode et repose sur les parties saillantes en forme d'ailettes. Application aux cellules d'électrolyse, notamment de chlorures de métaux alcalins.
