Abstract

Elément peu coûteux présentant une bonne résistance aux produits d'électrolyse. Il comprend : a. un agglomérat moulé de particules conductrices de carbone et/ou de graphite et de particules d'une résine de polymère thermoplastique fluorocarboné dans des proportions relatives en poids de 2,5 : 1 à 16 : 1, présentant une résistivité de masse inférieure à 1,57 x 10**-3 ohms.cm; b. cet agglomérat moulé comportant un corps principal et une chambre en évidement avec de multiples saillies conductrices espacées s'étendant à partir de la base de la chambre et permettant le contact et le passage du courant entre le corps et les autres éléments conducteurs, les saillies définissant de multiples canaux distributeurs de fluides ; c. des dispositifs communiquant avec la chambre en évidement et permettant l'introduction et l'évacuation de fluides. Application aux cellules d'électrolyse.
