Technical Field
The utility model relates to the technical field of solid hydrogen storage, in particular to a heatable solid metal hydrogen storage bottle.
Background
Some metals in nature have strong capability of capturing hydrogen, and under certain temperature and lower pressure conditions, the metals can absorb hydrogen in a large amount, react to generate metal hydride and release heat, and then the metal hydride is heated, and then the metal hydride is decomposed and the hydrogen stored in the metal hydride is released. These metals, which "take up" or desorb hydrogen gas, are referred to as hydrogen storage alloys.
Solid metal hydrogen storage is a heatable solid metal hydrogen storage bottle which can absorb hydrogen in metal materials by utilizing the characteristics of some metals, but the solid metal has poor thermal conductivity, is easy to expand when absorbing hydrogen, is easy to flow powder and leads the internal heat transfer to be slow.
