Abstract
Provided is a gas-phase hydrogen permeation test device capable of safely measuring hydrogen permeation behavior in a material under a high-pressure hydrogen atmosphere. The gas-phase hydrogen permeation test device includes a high-pressure hydrogen feeder, an analyzer, a primary-side pipe, a secondary-side pipe, a secondary-side pressure gauge, a primary-side shut-off valve, a primary-side discharge valve, a secondary-side discharge valve, a passive discharger, a secondary-side shut-off valve, and a controller configured to, when the pressure measured by the secondary-side pressure gauge reaches or exceeds a specific value, place the primary-side shut-off valve and the secondary-side shut-off valve into a closed state and the primary-side discharge valve and the secondary-side discharge valve into an open state.
