Hydrogen storage system using hydrogen storage material

Abstract

The present invention relates to a hydrogen storage system using a hydrogen storage material and can increase a heat exchanging efficiency by improving a contact frequency to the heat exchanger by vibrating the heat exchanger that is mounted in the hydrogen storage tank using the hydrogen storage material by using a vibrator to induce resonance vibration of the packed storage material powder.
