Description

technical field [0001] The invention relates to a method for manufacturing a hydrogen supply device, belonging to the field of hydrogen supply. Background technique [0002] The centralized gas supply system, also known as the central gas supply system, is a gas supply method that is more and more widely used by people. However, the pressure of the centralized gas supply system is generally not too high, because the gas pressure required by most instruments is not too high, and in many cases the pressure <1MPa is enough for use. In addition, for centralized gas supply, due to the longer gas pipeline, low-pressure gas supply is beneficial to reduce leakage and is conducive to safety management. [0003] However, some laboratories occasionally need to purchase some instruments and equipment that use high-pressure hydrogen for experiments, such as PCT devices for performance testing of hydrogen storage materials, which often require the use of high-purity hydrogen at a pres...

AI Technical Summary

Problems solved by technology

[0004] (1) There are moving parts, and its sealing parts need regular maintenance;

[0005] (2) There is greater noise and vibration;

[0006] (3) Pollution discharge exists;

[0007] (4) The purity of hydrogen will be reduced under the action of oil vapor;

[0008] (5) High energy consumption and high operating costs;

[0009] (6) Large footprint

[0010] In addition, sometimes the concentrated hydrogen supply of pipelines may have some impurity components in hydrogen that are higher than the standard content, which will affect the test results of the back-end hydrogen analysis instrument, and there is a need for hydrogen purification
