Problems solved by technology

[0004] The existing technical scheme uses thermocouple heating to control the temperature of solid hydrogen storage alloys. There are overshoots or hysteresis in the control process, and there may be frequent start and stop of thermocouples. The problem of temperature fluctuations leads to unstable hydrogen release rates. At the same time, the device has no clear cooling mechanism, the hydrogen storage alloy will release heat during the hydrogen absorption process, and the device has no better way to deal with it

Description

technical field [0001] The invention belongs to the technical field of hydrogen storage and supply devices, and in particular relates to a solid-state hydrogen storage and supply device for hydrogen refueling stations. Background technique [0002] As a clean and efficient energy, hydrogen energy has been widely valued in the field of transportation, and the application of hydrogen fuel cell vehicles is also being rapidly promoted. Therefore, the storage and supply of hydrogen in hydrogen refueling stations has become one of the key technologies in the field of hydrogen energy. The current main hydrogen storage methods are: high-pressure gaseous hydrogen storage, low-temperature liquid hydrogen storage, solid-state hydrogen storage and organic liquid hydrogen storage four hydrogen storage technologies. Solid-state hydrogen storage is to store hydrogen by hydrogen storage metals (alloys) absorbing a large amount of hydrogen at a certain temperature and lower pressure, and rea...
