Abstract

L'invention concerne une poudre catalytique composée de particules métalliques de support à revêtement poreux (12) qui enveloppe les particules métalliques (11). Ledit revêtement est composé soit d'un métal électrocatalytique, soit d'un métal électrocatalytique en phase continue en adjuvant avec une substance particulaire (14). L'invention concerne également une électrode produite avec la poudre catalytique ainsi qu'un procédé de fabrication de ladite électrode. L'intérêt de l'invention réside dans le fait qu'on applique en premier lieu le mélange de revêtement poreux à une poudre plutôt que directement sur un substrat métallique, créant ainsi une grande zone superficielle interne sur l'électrode et, par conséquent, des exigences moindres en matière de surtension.
