Self-regulating hydrogen generator
First Claim
1. A method for generating hydrogen comprising the steps of:
- providing a chamber holding a fuel solution, said fuel solution generating hydrogen and a discharged fuel solution via a chemical reaction as part of a hydrogen generation process;
providing a catalyst chamber containing a catalyst that accelerates the generation of hydrogen when in contact with said fuel solution, said catalyst chamber being disposed within said chamber; and
monitoring at least one parameter of said hydrogen generation process; and
providing relative movement between said catalyst chamber and said chamber so as to vary the rate of hydrogen generation by bringing more or less of said catalyst in said catalyst chamber into contact with said fuel solution.

Abstract
A hydrogen generating system regulates its rate of hydrogen generation by monitoring one or more parameters of the hydrogen generation process and then providing relative movement between the fuel tank and the catalyst chamber so as to increase or decrease the rate of hydrogen generation.
In the disclosed embodiments, the catalyst chamber is disposed in a tank containing the fuel. The relative movement provided moves the catalyst chamber toward the fuel solution so as to increase the rate of hydrogen generation and moves the catalyst chamber away from the fuel solution to decrease such generation. Advantageously, such self-regulation can be provided without an external power source and can be varied to meet the requirements of different commercial applications. The overall system can be readily fabricated using commercially available parts.
