Title
(EN) FUEL CELL ELECTRODE
(FR) ELECTRODE DE PILE A COMBUSTIBLE
Abstract
(EN)
A fuel cell (1) having an electrode comprising an electrocatalyst (32) on a support, wherein the support is a mesh (30) of conductive material such as a metal, metal alloy and metal composite (e.g. titanium or titanium alloy), is disclosed, as well as a method of operating such a fuel cell by contacting a fuel and an oxidant on said electrode. The electrolyte of the fuel cell may be an ion exchange membrane.
(FR)
L'invention concerne une pile à combustible (1) dotée d'une électrode comprenant un électrocatalyseur (32) sur un support, ce support étant un réseau (30) de matériau conducteur. L'invention concerne également un procédé d'activation d'une pile à combustible de ce type par mise en contact d'un combustible et d'un oxydant sur ladite électrode.
