Description

technical field [0001] The invention relates to the field of solid-state hydrogen storage, in particular to a system and method for automatically controlling hydrogen absorption and desorption of solid-state hydrogen storage materials. Background technique [0002] Hydrogen energy is a kind of clean energy. At present, the application of hydrogen energy is relatively mature in the world, but the storage and transportation of hydrogen are common technical bottlenecks. The pressure of foreign high-pressure gaseous hydrogen storage can reach 70MPa, and the pressure of domestic hydrogen storage cylinders can reach up to 35MPa. Although the hydrogen storage density has been increased, the requirements for the material of the cylinder are higher, and the risk factor is also higher. Cryogenic liquid hydrogen storage needs to be stored at -253°C. Both of these two hydrogen storage methods have technical and economic disadvantages. Solid hydrogen storage materials have become a favo...

AI Technical Summary

Problems solved by technology

Solid hydrogen storage materials have become a favored method of hydrogen storage due to their large hydrogen storage capacity and high safety. The medium is unevenly heated, the control effect of hydrogen absorption and desorption is poor, and the application range is narrow, etc.
