Abstract
A hydrogen generator includes 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.
Claims8
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.
