Problems solved by technology

[0004] However, metal hydrides will generate a large amount of heat during the hydrogen absorption process. If the heat generated is not dissipated in time, it will affect the hydrogen absorption speed. In addition, the volume of the metal hydride will expand by about 25% after hydrogen absorption. The hydride will absorb heat when hydrogen is released; in addition, the hydrogen storage material will continue to be pulverized into fine powder particles during the cycle of hydrogen absorption and desorption, and will be aggregated and compacted in certain parts of the hydrogen storage tank under the action of gravity. The heat and mass transfer performance is reduced, which affects the hydrogen absorption and desorption rate; at the same time, the excessively aggregated hydrogen storage material powder will cause irreversible damage to the tank body after hydrogen absorption and expansion, resulting in damage to the metal hydride hydrogen storage tank

Description

technical field [0001] The invention relates to the technical field of hydrogen storage devices, in particular to a metal hydride hydrogen storage tank with strong stress resistance and good heat and mass transfer effects. Background technique [0002] With the sharp increase in energy demand around the world, the problem of greenhouse gas emissions and global climate change is becoming more and more serious. Compared with fossil fuels, hydrogen energy has the advantages of high energy conversion efficiency, no pollution products during use, and abundant hydrogen reserves. Therefore, hydrogen energy is considered to be the most promising clean energy in the 21st century. For various applications of hydrogen energy, the storage of hydrogen is inevitably involved. [0003] At present, hydrogen storage methods mainly include: high-pressure gaseous hydrogen storage, low-temperature liquid hydrogen storage and metal hydride hydrogen storage. Although high-pressure gaseous hydro...
