CA 2241230
This invention covers a cathodic element free from asbestos fibres that can be obtained by deposition after filtration through a porous medium of an aqueous suspension comprising electrically conductive fibres, at least one cationic polymer, at least one electrocatalytic agent, at least one pore-forming agent and at least one binder selected from among the fluoropolymers. The invention also covers a method for preparing such a cathodic element.
La présente invention a pour objet un élément cathodique dépourvu de fibres d'amiante susceptible d'être obtenu par un dépôt par filtration à travers un support poreux, d'une suspension aqueuse comprenant des fibres conductrices de l'électricité, au moins un polymère cationique, au moins un agent électrocatalytique, au moins un agent porogène et au moins un liant choisi parmi les polymères fluorés. La présente invention a de même pour objet un procédé de préparation d'un tel élément cathodique.
