FIELD: chemistry.
SUBSTANCE: invention relates to the field of storing and withdrawal of hydrogen with the application of porous components, interacting with hydrogen with the reversible formation of metal hydrides. A reservoir for the accumulation and withdrawal of hydrogen by a reversible reaction of hydration/dehydration consists in a heat-insulated chamber, which contains a multitude of hydrogen-accumulating elements in the form of hydrides, with each element having a surface for exchange with gaseous hydrogen, from one side, and a surface of heat-exchange from the other side, and a multitude of heat-accumulating elements for the accumulation and return of heat, connected with the reversible hydration/dehydration reaction.
EFFECT: invention provides economical and practical hydrogen accumulation.
