AB  - As a commonly used liner material for fully reinforced, carbon-fiber-composite 
      hydrogen storage cylinders, polyamide 6 (PA6) needs to meet the required hydrogen 
      permeation index during use; otherwise, it may adversely affect the safe use of 
      hydrogen storage cylinders. The hydrogen permeability of PA6 under different 
      temperatures and pressures was tested, and the variations in its hydrogen 
      permeability were investigated. Additionally, the hydrogen permeability of PA6, 
      polyamide 11 (PA11), and high-density polyethylene (HDPE) at a temperature of 288 
      K and a pressure of 70 MPa was tested, and the differences in hydrogen 
      permeability among these commonly used liner materials for type IV on-board 
      hydrogen storage cylinders were studied. The results reported herein indicate 
      that both the hydrogen permeability and diffusion coefficient of PA6 increase 
      with rising test temperature but decrease with increasing pressure. The 
      solubility coefficient of PA6 shows no significant change with varying test 
      temperatures and pressures. At a test temperature of 288 K and a pressure of 70 
      MPa, among the three materials, PA6 has slightly stronger hydrogen permeation 
      resistance than PA11, while HDPE has the least resistance. These research 
      findings can serve as valuable reference data for evaluating the hydrogen 
      permeability of liner materials.
