Hydrogen storage in metal hydrides for the hydrogen supply of fuel cell car
Description
Hydrogen storage remains an issue for its use in mobile applications. Despite its weight, storage in metal hydrides presents advantages in term of safety and volumic capacity. In this work, several families of hydrides have been studied to answer to the working conditions of a main tank or a buffer tank for cold start. The thermodynamic properties of LaNi5 and TiFe type hydrides have been adjusted by suitable substitutions allowing to obtain potentially usable compounds for both kinds of tanks. In order to increase the weight capacity, the effect of M element on thermodynamics properties of lighter hydrides based on Ti-V-M solid solutions (M=Mn, Fe, Co, Ni) has been studied showing the best hydrogenation properties for the Fe compound. Finally, the discovery of hydrogen reactivity of the Ti3Si compound opens new routes. (author)
Abstract (French)
Le stockage d'hydrogene reste un defi pour son utilisation comme carburant dans les applications mobiles. Malgre une masse elevee, le stockage dans les hydrures metalliques presente des avantages en termes de securite et de capacite volumique. Dans ce travail, plusieurs familles d'hydrures ont ete etudiees pour repondre au cahier des charges d'un reservoir principal ou d'un reservoir tampon de demarrage a froid. Les proprietes thermodynamiques des hydrures type LaNi5 et TiFe ont ete ajustees par le jeu de substitutions permettant d'obtenir des composes potentiellement utilisables dans ces deux types de reservoirs. Afin d'augmenter la capacite massique, l'influence de l'element M sur les proprietes thermodynamiques d'hydrures plus legers de type solution solide Ti-V-M (M=Mn,Fe,Co,Ni) a ete etudiee montrant de bonnes proprietes d'hydrogenation pour le compose au fer. Enfin, la decouverte de la reactivite vis-a-vis de l'hydrogene du compose Ti3Si ouvre une nouvelle voie. (auteur)Files
