HYBRID HYDROGEN STORAGE CONTAINER AND METHOD OF STORING HYDROGEN IN CONTAINER

摘要

A hybrid hydrogen storage container and a method of storing hydrogen in the container, the container comprising a pressure vessel (1) allowed to fill hydrogen therein at a pressure of 30 MPa or higher and having a reinforced layer (2) and a liner layer (3), the pressure vessel (1) further comprising, therein, a hydrogen occlusion body and a carrier (4) for supporting the hydrogen occlusion body, wherein the maximum hydrogen occlusion amount (.alpha.m) of the hydrogen occlusion body per unit volume is .alpha.m >= 100 (kg/m3) and volume ratio (X) of the hydrogen occlusion body to the inside volume of the pressure vessel (1) is 5(%) <= X <= 20(%), where X = 100 .cndot. Vm/Vi (%), Vi: inside volume (L) of pressure vessel, Vm: volume (L) of hydrogen occlusion body in pressure vessel.
