Hydrogen supplying device for fuel cell

A hydrogen supplying device for a fuel cell, comprising:

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

A hydrogen supplying device for a fuel cell, comprising:

• a hydrogen occlusion tank in which a hydrogen occlusion alloy is contained, said hydrogen occlusion alloy being capable of occluding and discharging hydrogen which is used as a fuel for said fuel cell;
• a heating unit which is used for heating said hydrogen occlusion tank by supplying a heating medium, which has been heated by using waste heat from said fuel cell and whose temperature is controllable, to said hydrogen occlusion tank to discharge hydrogen from said hydrogen occlusion alloy;
• and
• a required quantity of heat calculation unit which calculates a quantity of heat required by said hydrogen occlusion tank based on an amount of hydrogen supplied from said hydrogen occlusion tank, wherein
• said heating unit is controlled depending on the required quantity of heat calculated by said required quantity of heat calculation unit.
