Abstract
A hydrogen generator comprising a plurality of a fuel pellets (10) containing a hydrogen-generating compound such as ammonia borane, a case serving as a pressure-resistant container for containing the fuel pellets, and a controller for controlling hydrogen generation from the fuel pellets. This hydrogen generator generates hydrogen from the hydrogen-generating compound by a chemical reaction. The periphery of the fuel pellet is surrounded by a member including a thin plate of metal aluminum such as aluminum foil (18) on its surface.
Claims10
A hydrogen generator for generating hydrogen from a hydrogen generating compound by a chemical reaction, characterized in that it comprises:
- a plurality of fuel pellets including the hydrogen generating compound;
- a pressure-resistant container for storing the plurality of fuel pellets;
- and
- a controller for controlling hydrogen generation from the fuel pellets, wherein
- the periphery of the fuel pellet is enclosed with a member including a thin plate of metal aluminum on its surface.
A fuel pellet body stored in a pressure-resistant container in a hydrogen generator for generating hydrogen from a hydrogen generating compound by a chemical reaction, comprising:
- a hydrogen generating compound compacted into a cylindrical shape;
- and
- a member including a thin plate of metal aluminum on its surface to enclose the periphery of the hydrogen generating compound.
A hydrogen generator for generating hydrogen from a hydrogen generating compound by a chemical reaction, characterized in that it comprises:
- a plurality of fuel pellets including the hydrogen generating compound;
- a pressure-resistant container for storing the plurality of fuel pellets;
- and
- a controller for controlling hydrogen generation from the fuel pellets;
- wherein the controller comprises a non-volatile memory that is arranged to record the usage state of each pellet, the controller being arranged to change the value in the non-volatile memory for each pellet, after it has been ignited, to a value that indicates that it is used up.
