A review on hydrogen permeability of polymer liner materials for type Ⅳ on-board hydrogen storage cylinders
This paper reviewed the permeation mechanism of gases in polymer materials in detail.The test methods for hydrogen permeability of polymer linings of Type Ⅳ hydrogen storage cylinders and domestic and international test stan-dards were briefly introduced.The effects of test temperature,test pressure,and polymer material properties on the hy-drogen permeability of the liner material were further discussed along with the trend of the development direction in fu-ture.
