Description

technical field [0001] The invention relates to a device for activating high-temperature hydrogen storage alloys and charging and discharging hydrogen. Background technique [0002] As a secondary new energy source, hydrogen energy is attracting the attention of scientists all over the world. With the advancement and development of hydrogen fuel cell vehicles, portable power and backup power technologies, hydrogen is more widely used as a mobile energy carrier. Therefore, the problem of hydrogen storage and transportation has become increasingly prominent. Currently, hydrogen storage options are limited. The gas compression method is convenient to use, but it has a large volume, high pressure and low storage density, and is dangerous; although liquid hydrogen storage has a high storage energy density, it requires heat insulation and consumes a lot of energy. Metal alloy materials for hydrogen storage have the advantages of both, and are relatively safe, energy-saving and c...
