activation energy of hydride composites. Additionally, the degree of conversion and

volume of hydrogen released in hydrolysis reactions and the influence of magnesium

chloride concentration on these parameters were investigated. The synthesized for the

first time hydride composite MgZr V O C is proposed for use in hydrogen storage

devices for hydrogen transport and storage. The synthesized composites can also be

used in hydrolysis hydrogen generation devices for powering fuel cells.
