This paper deals with the propagation of a shockwave in the hydrogen vessel. The aim of this research is the improvement of safety to store hydrogen. The shockwave is generated by the high explosive of the proper quantity and is controlled by a PMMA card gap. The shockwave propagation is visualized by using a high-speed camera image and movie. Shooting procedure is by a shadow graph method. We succeeded in photography of shockwave propagation and combustion phenomenon. Results are then compared with other medium.
