Abstract

A hydrogen supplying device for a fuel cell includes a hydrogen occlusion tank in which a hydrogen occlusion alloy is contained, the hydrogen occlusion alloy being capable of occluding and discharging hydrogen which is used as fuel for a fuel cell; a hydrogen tank in which hydrogen to be supplied to the fuel cell can be stored in a compressed state; a heating unit which supplies heat to the hydrogen occlusion tank; a hydrogen supply line through which a flow of hydrogen supplied from the hydrogen occlusion tank and a flow of hydrogen supplied from the hydrogen tank can be merged to be supplied to the fuel cell; and a flow rate controlling device which controls a flow rate of hydrogen supplied from the hydrogen occlusion tank and/or a flow rate of hydrogen supplied from the hydrogen tank.
