Title
(EN) PALLADIUM-PLATINUM SYSTEM FOR USE AS HYDROGEN STORAGE MATERIAL AND/OR ELECTROCATALYST, PREFERABLY IN FUEL-CELLS
(FR) SYSTÈME DE PALLADIUM-PLATINE DESTINÉ À ÊTRE UTILISÉ EN TANT QUE MATÉRIAU DE STOCKAGE D'HYDROGÈNE ET/OU EN TANT QU’ÉLECTROCATALYSEUR, DE PRÉFÉRENCE DANS DES PILES À COMBUSTIBLE
Abstract
(EN)
The present invention relates to palladium-platinum system consisting of palladium layer covered with a platinum overlayer consisting of 1 to 10 platinum monolayers deposited on palladium for use as hydrogen storage. Such system can be used in fuel cells, hydride batteries and supercapacitors. A method for increasing hydrogen absorption kinetics of hydrogen absorption/desorption process is also disclosed.
(FR)
La présente invention concerne un système de palladium-platine constitué d’une couche de palladium recouverte d'une surcouche de platine constituée de 1 à 10 monocouches de platine déposées sur du palladium et destiné à être utilisé en tant que stockage d'hydrogène. Un tel système peut être utilisé dans des piles à combustible, des batteries d'hydrure et des supercondensateurs. L'invention concerne également un procédé permettant d’augmenter la cinétique d'absorption d'hydrogène d’un procédé d'absorption/de désorption d'hydrogène.
