The application patent with publication number of CN113188974B discloses a high-pressure hydrogen permeation test device and a high-pressure hydrogen permeation test method for IV gas cylinder liner materials, and the permeation test of the patent is mainly used for realizing test items under constant pressure and circulating pressure, but the influence on the permeation caused by the separation degree between a fiber winding layer and a plastic liner, which is proposed above, cannot be solved.
Therefore, it is necessary to provide a device for testing the influence of the permeability of a hydrogen storage bottle for producing hydrogen by electrolysis of water, which can detect the influence of the degree of separation between a fiber wound layer and a plastic liner of the hydrogen storage bottle on the permeability.
