Abstract
The VH4 container is used for the container for the compression hydrogen car fuel device, and to use the polymeric material, the generation of the hydrogen penetration is expected. The permeation testing by various condition change was executed for the hydrogen penetration situation awareness. The amount of the hydrogen penetration is different according to a result, a container material, an environmental temperature, and the filling pressure. It applies to the relational expression of arrhenius in the gas transmission coefficient in the container shape.
