Abstract

La présente invention concerne une anode constituée d'un corps fritté poreux en poudre de tantale, chaque particule de la poudre étant revêtue d'une couche d'au moins l'un des métaux suivants : vanadium, molybdène et palladium. Cette anode permet d'obtenir un courant inverse et un courant de fuite de faible valeur dans un condensateur électrolytique solide. La présente invention prévoit également un procédé efficace de préparation d'une telle anode.
