Abstract

Matériau électroactivé comprenant des fibres dont une partie au moins est conductrice d'électricité, un liant, caractérisé en ce qu'il comprend en outre un agent électrocatalytique constitué par des particules formées d'oxyde de ruthénium, de platine, de palladium, d'iridium, ou leur mélange, ou de l'un ou plusieurs desdits oxydes, répartis au moins en partie, sur un support conducteur d'électricité. Le matériau électroactivé est utilisable notamment en tant qu'élément cathodique d'une cellule d'électrolyse, et en particulier d'une cellule d'électrolyse de solutions aqueuses de chlorure de sodium. La présente invention concerne de même un matériau composite comprenant: (a) un matériau à porosité élevée, (b) le matériau électroactivé précité. L'invention concerne enfin un matériau composite comprenant d'une face vers l'autre: (a) une surface métallique de porosité élevée, (b) le matériau électroactivé précité, (c) un séparateur.
