NOVELTY - The shield has an n-type semiconductor layer arranged on a reinforcement layer and laminated on a p-type semiconductor layer. An electrode is arranged in upper and lower parts of a hydrogen repellent layer. The n-type semiconductor layer and the p-type semiconductor layer are laminated on the hydrogen repellent layer. A hydrogen absorption layer is arranged on the hydrogen repellent layer. An upper electrode is fixed in the hydrogen absorption layer. A catalyst layer is arranged on the hydrogen absorption layer. The n-type semiconductor layer is an n-type organic semiconductor layer.    USE - Hydrogen permeation shield for a hydrogen storage device (claimed).    ADVANTAGE - The shield prevents hydrogen of a hydrogen storage container from being leaked. The shield prevents the hydrogen storage container from being damaged due to corrosion. The shield has prolonged service lifetime. The shield improves stability of the hydrogen storage container.
