Abstract

La présente invention concerne un article (20) en graphite qu'on utilise pour produire un ensemble (6) électrodes à membrane constitué d'une paire d'électrodes et d'une membrane (550) échangeuse d'ions placée entre les électrodes. Au moins une des électrodes est formée d'une feuille de matière comprimée de particules expansées de graphite comportant une pluralité de canaux transversaux (20) pour le fluide qui traversent la feuille entre les première et deuxième surfaces opposées de la feuille, une des surfaces opposées venant buter contre la membrane (550) échangeuse d'ions lorsqu'on l'utilise dans un ensemble (6) électrodes à membrane. Au moins un certain nombre de canaux (20) pour le fluide sont reliés entre eux pour permettre au fluide de circuler entre ces derniers.
