NOVELTY - Hydrogen supply tank comprises hydrogen-generating container(s) (10), which receives a hydrogen-generating material capable of heat emission and dehydrogenation under heating, and has hydrogen discharge path (12) that allows discharge of the generated hydrogen, on its wall surface; and divided sections, where hydrogen-generating container is mounted to each section. It stores the hydrogen discharged from the hydrogen-generating container and supplies the hydrogen to external sites.    USE - The hydrogen supply tank is used for supplying hydrogen to external sites. It is useful for hydrogen supply apparatus for hydrogen-consuming device, which is a vehicle driven partially or totally by power transmitted from fuel cell (claimed), electric power generation system e.g. fuel cell, particularly polymer electrolyte fuel cell, or hydrogen engine using hydrogen combustion energy. Vehicle is particularly fuel cell vehicle.    ADVANTAGE - The hydrogen supply tank generates hydrogen efficiently from dehydrogenatable material that emits heat spontaneously when heated initially without any separated solid or liquid catalyst, stores hydrogen in a low-pressure low-weight mode, and supplies hydrogen to hydrogen-consuming device. The divided section enables the hydrogen supply tank to endure a high pressure applied to it. The hydrogen supply tank is capable of minimizing an increase in weight caused by wirings and controller installment. It realizes generation, storage, and supply of hydrogen with high efficiency; is maintained in a low-pressure and low-weight mode; and easily controls the exothermic reaction and operation during the generation of hydrogen from the hydrogen-generating material. The hydrogen-generating material capable of heat emission and dehydrogenation under heating generates hydrogen continuously via self-made heat emission without additional heating, once it is initially heated to generate hydrogen.
