摘要：

The hydrogen permeability of the materials under high pressure is an important parameter for the safety of the plastic liner hydrogen storage cylinder. This study introduces the first 99 MPa hydrogen permeability testing apparatus developed independently in China，which solves the key technical problems such as high-pressure hydrogen sealing and precise measurement of the trace amount of hydrogen. The hydrogen permeability test of non-metallic materials under the working pressure of 0.1 MPa-99 MPa and the temperature of -40 ℃-85 ℃ can be conducted using the apparatus. Using the testing apparatus，the hydrogen penetration tests of the plastic liner materials under four different working conditions，including（87.5 MPa，15 ℃），（80.5 MPa，55 ℃），（70 MPa，85 ℃）and（70 MPa，-40 ℃），were carried out，and the reliability of the testing apparatus was verified. This work provides test methods and technical support for the hydrogen permeation test of plastic liner materials and the development of domestic plastic liner materials. © 2023 Science Press.
