Title
(EN) GASEOUS DIFFUSION ELECTRODE AND USE IN CATALYSED ELECTROCHEMICAL PROCESSES
(FR) ELECTRODE A DIFFUSION GAZEUSE ET APPLICATION AUX PROCESSUS ELECTROCHIMIQUES CATALYSES
Abstract
(EN)
The invention concerns a gaseous diffusion electrode comprising an activated carbon fibre fabric (12) having a first surface coated with a hydrophobic material (14) and a second surface whereon are directly fixed catalyst particles (16) dispersed substantially homogeneously on the fibres. The electrode is useful in an electrochemical cell unit of a fuel cell with proton-exchanging membrane, or in an electrochemical reactor for example for making chlorine-soda.
(FR)
Une électrode à diffusion gazeuse comprend un tissu (12) en fibres de carbone activé ayant une première face enrobée de matériau hydrophobe (14) et une deuxième face sur laquelle sont fixées directement des particules de catalyseur (16) dispersées de façon sensiblement homogène sur les fibres. L'électrode est utilisable dans une cellule électrochimique de pile à combustible à membrane échangeuse de protons, ou dans un réacteur électrochimique par exemple pour la fabrication de chlore-soude.
