Patent ID: 8137627

Claim:
A hydrogen generator comprising: a plurality of fuel sticks each of which includes a hydrogen release compound configured to generate hydrogen by a chemical reaction; a pressure-resistant container configured to store therein the plurality of fuel sticks; and a controller configured to carry out control in such a manner that hydrogen is generated selectively from the plurality of fuel sticks, wherein at least one fuel stick includes: an exothermic resistive element arranged in the center of the fuel stick, and configured to generate heat by causing a current to flow therethrough; an exothermic compound arranged outside the exothermic resistive element, and configured to generate heat by the exothermic resistive element, and heat the hydrogen release compound; the hydrogen release compound arranged outside the exothermic compound, and configured to generate hydrogen; and a porous heat insulating material arranged outside the hydrogen release compound, and permeable to hydrogen, and an external shape of the fuel stick is one of a cylindrical shape and shape of a hexagonal cylinder.
