Description

technical field

[0001] The invention relates to the field of hydrogen energy power supply, in particular to a small and light cryogenic high-pressure hydrogen storage power supply system based on cryogenic high-pressure hydrogen storage. Background technique

[0002] At present, domestic small machines such as small unmanned aerial vehicles and unmanned ships are developing towards the direction of power supply by hydrogen energy, so a hydrogen storage power supply system is usually installed on small machines. The fuel cell is composed of a hydrogen storage device capable of storing hydrogen and supplying hydrogen to the hydrogen fuel cell. Existing hydrogen storage devices usually include high-pressure hydrogen storage devices, liquid hydrogen storage devices, and medium-sized cryogenic high-pressure hydrogen storage devices.

[0003] Due to the limitation of hydrogen storage density, the high-pressure hydrogen storage device has relatively insufficient battery life, and ...
