Outline of Final Research Achievements

Establishing a superb hydrogen storage method is needed in order to realize hydrogen energy society. The method which uses metal hydride enables us to store hydrogen compact and safety. However, the metal hydride swells when it absorb hydrogen and pushes the vessel of the hydride. The countermeasure for such the vessel deformation which is brought by the metal hydride swelling is needed. In this study, the in-situ visualization in micro-/macroscale was conducted. The difference of the bed swelling behavior in the kind of the metal hydride, which should influence on the stress development process, was revealed.
