Hydrogen propelled vehicles and fundamentally new magnesium-based hydrogen storage alloy materials (12) which for the first time make it feasible and practical to use solid state storage and delivery of hydrogen to power internal combustion engine or fuel cell vehicles. These exceptional alloys have remarkable hydrogen storage capacity of well over 6 weight % coupled with extraordinary absorption kinetics such that the alloy powder absorbs 80 % of its total capacity within 10 minutes at 300C and a cycle life of at least 500 cycles without loss of capacity or kinetics.
L'invention concerne des véhicules à propulsion par hydrogène et des matériaux (12) de stockage d'hydrogène comprenant des alliages fondamentalement nouveaux à base de magnésium, permettant pour le première fois la mise en oeuvre pratique d'un stockage sous forme solide et d'une distribution d'hydrogène pour l'alimentation de véhicules à moteur à combustion interne, ou de véhicules à piles à combustible. Ces alliages exceptionnels présentent une capacité de stockage d'hydrogène remarquable, dépassant largement 6 % en poids, associée à une cinétique d'absorption exceptionnelle, la poudre d'alliage absorbant 80 % de sa capacité totale en 10 minute à 300 ·C, et à un cycle de vie comptant au moins 500 cycles sans pertes de la capacité cinétique.
