Abstract
(EN)



The invention relates to a material for reversible hydrogen storage comprising
a complex hydride based on one or more anions selected among BH4 -, MgH3 -,
MH4 - and MH6 3- (M = Al, Ga, In), and one or more cations, where the material
has obtained amended stability due to substitution of the complex hydride
phase itself. The invention also relates to a process for preparation of the
material and use thereof, and a process for reversible hydrogen storage.
