Abstract
A hydrogen storage apparatus M stores a liquid hydrogen tank , hydrogen filling passage that fills liquid hydrogen in to the liquid hydrogen tank, a degassing passage provided with a relief valve V that opens when the pressure of hydrogen gasified in the liquid hydrogen tank reaches a predetermined level, and a hydrogen occlusive tank that accommodates a hydrogen occlusive alloy for storing the gasified hydrogen. When liquid hydrogen is being filled into the liquid hydrogen tank , the pressure in the hydrogen occlusive tank is lowered using a duct , a cooling fan , and a conduit for cooling the hydrogen occlusive tank . Accordingly, the filling time is shortened and the fuel efficiency is improved.
