The polymeric material is used as layer of the VH4 container for the compressed hydrogen car fuel device, so that it is predicted that the amount of hydrogen permeation is different between the different environmental temperature conditions. The permeation test of SAE proposal is carried out to take the basic data for the hydrogen permeation amount value of the VH4 container for 70 MPa, the following results are obtained. The amount of the hydrogen permeation is different in the case of different polymeric materials. The amount of the hydrogen permeation is increased according to the increase of environmental temperature. The amount of the hydrogen permeation is increase according to the increase of filling pressure. Moreover, in the case of gas transmission coefficient in the container shape, it is confirmed that the temperature influence of gas transmission coefficient is in accordance with the relational expression of Arrhenius law to the polymer.
