Problems solved by technology

[0005] Due to structural design reasons, the compression ratio range of the mechanical hydrogen compression system is usually small. To achieve a higher pressure output, it often requires the cooperation of more stages of different types of mechanical hydrogen compressors to achieve it. lead to bulky system
In addition, the traditional mechanical compression scheme itself does not involve the storage function of hydrogen, which requires a large storage tank to meet its use requirements
[0006] With the increasing demand for high-pressure hydrogen in the market, the shortcomings of traditional mechanical hydrogen compression methods have been increasingly exposed

Abstract

The invention provides a continuous-output static-hydrogen compression, storage and filling integration system and belongs to the technical field of hydrogen fuel. The integration system includes a hydrogen source input device, a filling device and at least one hydrogen boosting and storage unit, wherein each hydrogen boosting and storage unit includes a static-hydrogen compression device and a pressurized-hydrogen storage device; the static-hydrogen compression device correspondingly communicates with a hydrogen source input device and the pressurized-hydrogen storage device; and the pressurized-hydrogen storage device further communicates with the inlet end of the filling device or the hydrogen inlet end of the next static-hydrogen compression device. The integration system has no movingparts, completely uses a heat driving method to realize the pressurizing of hydrogen, has compact and quiet design, high reliability and low risk of leakage, can simultaneously improve the purity ofhydrogen in the process of compression, and realizes the continuous output of compressing hydrogen through the hydrogen sucking and discharging method of alternating multiple tanks; and when multiplestages are in parallel operation, the hydrogen compression and conveying capacity of the system is greatly improved and the practicability is improved.

Description

technical field [0001] The invention belongs to the technical field of hydrogen fuel, and in particular relates to a continuous output static hydrogen compression, storage and filling integrated system. Background technique [0002] Any device driven by hydrogen fuel cells, such as fuel cell vehicles, backup power sources, etc., needs to use hydrogen and oxygen as its "fuel". Oxygen can be obtained from the air, while hydrogen needs to be stored in advance. When needed Release it again. At present, the high-pressure hydrogen technology solution has become the first solution for the fuel cell hydrogen supply system due to its mature technical route and good dynamic response performance of the hydrogen supply system. [0003] The most mature method of generating high-pressure hydrogen currently on the market mainly adopts the method of mechanical compression, which causes the volume change of the gas storage space through the movement of the piston or diaphragm, thereby short...
