A catalytic powder comprising a plurality of support metal particles with a porous coating (12) surrounding the metal particles (11), the porous coating comprising either an electrocatalytic metal or an electrocatalytic metal continuous phase in admixture with a particulate material (14). An electrode made with the catalytic powder and a method to make the electrode is also disclosed. The present invention is advantageous because the porous coating mixture is first applied to a powder rather than being applied directly to a metal substrate, thereby creating a large internal surface area on the electrode and accordingly, lower overpotential requirements.

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.
