Abstract

L'INVENTION CONCERNE UNE ELECTRODE POREUSE QUI CONTIENT DU MOINS UNE COUCHE CATALYTIQUE POREUSE CONTENANT DU METAL NOBLE CATALYTIQUEMENT ACTIF, DU CARBONE ET UN LIANT POLYMERE AINSI QU'UN COLLECTEUR METALLIQUE POREUX SE TROUVANT DU COTE ELECTROLYTE DE CETTE COUCHE. CONFORMEMENT A L'INVENTION, LA COUCHE CATALYTIQUEMENT ACTIVE A UNE EPAISSEUR DE MOINS DE 80MM ALORS QUE LES PARTICULES DE METAL DANS LA COUCHE SE TROUVENT SUR LA SURFACE ETOU DANS LES PORES D'UNE PARTIE DES PARTICULES DE CARBONE ET QUE L'AUTRE PARTIE DES PARTICULES DE CARBONE NE CONTIENT PAS DE PARTICULES DE METAL. L'INVENTION COMBLE LA LACUNE D'UNE ELECTRODE DU TYPE DECRIT, AVEC UNE TENEUR EN METAL NOBLE FORTEMENT REDUITE, TOUT EN CONSERVANT LES BONNES PRESTATIONS EN CE QUI CONCERNE LE RENDEMENT, LA DENSITE D'ENERGIE ET LA SIMPLICITE DE FABRICATION.
