ADIABATIC TANK FOR METAL HYDRIDE

摘要

PROBLEM TO BE SOLVED: To provide a hydrogen-storing tank that is easy to manufacture and allows for quick kinetic absorption of hydrogen, and that has small variations in volume and has a low cost in terms of material and energy.SOLUTION: The hydrogen-storing tank includes a hydrogen inlet (21) and a hydrogen outlet (22) in communication with at least one solid body (10) allowing for exothermal absorption and endothermal desorption of hydrogen. At least one solid body is made of a compacted material containing light metal hydride and a heat-conducting matrix, and at least one solid body is in heat-transfer relation with at least one heat recovery material (42) free from salt or molten salt compounds, and capable of absorbing heat generated by hydrogen absorption and of releasing the absorbed heat so as to provide heat for hydrogen desorption.
