Description

Technical Field

[0001] The utility model relates to the technical field of filling devices, in particular to a filling device for solid hydrogen storage. Background Art

[0002] Solid-state hydrogen storage is a new technology that uses solid materials to store hydrogen. The principle is to store hydrogen in solid materials through physical adsorption or chemical reaction of solids on hydrogen. These solid hydrogen storage materials mainly include carbonaceous materials, metal hydrides, coordinated hydrides, metal organic framework materials and hydrogen hydrates. During the solid-state hydrogen storage process, a filling device needs to be fixedly connected to the feed pipe of the hydrogen storage tank before hydrogen can be input into the hydrogen storage tank.
