One of technical problems in this area is its effective storage. MgH2 is very perspective material whose main advantage is high hydrogen storage capacity (theoretically 7.6 wt. % H2). However, there are negative features of this material as a hydrogen storage medium: before all, it is its poor hydrogen de-sorption kinetics. Therefore, much effort has been devoted in the past to find out possible ways how to enhance the MgH2 de-sorption rate and how to shift this material close to technical applications. It is known that nickel and Mg2Ni enhance hydrogen de-sorption from MgH2. This paper continues our previous works on hydrogen de-sorption from Mg-Ni –based materials. It is devoted to the investigation of separate catalytic effect of Mg2NiH4 and Mg2Ni upon the hydrogen de-sorption from the principal component of the material - MgH2. It was found that catalytic efficiency of Mg2NiH4 is much higher than that of Mg2Ni. Pracoviště Ústav fyziky materiálu Kontakt Yvonna Šrámková, sramkova@ipm.cz, Tel.: 532 290 485 Rok sběru 2012
