Abstract:
A hydrogen generator includes a container having a gas outlet that is configured to contain a soluble chemical fuel that reacts with a catalyst to generate hydrogen. A control cylinder is attached to the container and comprises a piston configured to travel axially within the control cylinder, a pole attached to the piston and extending into the container, a catalyst holder provided within the container and connected to the pole, resilient means biasing the catalyst holder towards a bottom of the container, and a gas inlet port. A gas flow line is in fluid communication with the gas outlet and has a first end in fluid communication with the gas inlet port, a second end configured to feed hydrogen to a hydrogen-consuming device, and a two-way valve provided to allow fluid communication between the first and second ends of the gas flow line to be selectably established or cut off.

Claim (Index 1):
A hydrogen generator comprising:\n a container configured to contain a solution of a soluble chemical fuel that reacts with a catalyst to generate hydrogen, the container having a gas outlet to allow generated hydrogen to leave the container; a control cylinder having a first end attached to a top of the container and comprising\n a piston configured to travel axially within the control cylinder, the piston separating the control cylinder into two chambers: a first chamber defined between the piston and the first end of the control cylinder, and a second chamber defined between the piston and a second end of the control cylinder, \n a pole attached to the piston and extending into the container, \n a catalyst holder provided within the container and connected to the pole, the catalyst holder configured to secure a solid piece of the catalyst that reacts with the soluble chemical fuel to generate hydrogen, \n resilient means biasing the catalyst holder towards a bottom of the container, and \n a gas inlet port configured to allow hydrogen into the first chamber; \n a gas flow line in fluid communication with the gas outlet of the container, the gas flow line having\n a first end in fluid communication with the gas inlet port of the control cylinder, \n a second end configured to feed hydrogen generated in the container to a hydrogen-consuming device, and \n a two-way valve provided to allow fluid communication between the first end and the second end of the gas flow line to be selectably established or cut off, \n wherein in use, a free end of the solid piece of the catalyst secured to the catalyst holder is immersed in the solution in the container, wherein rate of hydrogen generation in the container is determined by a depth of submergence of the catalyst in the solution, and wherein the depth of submergence is determined by demand for hydrogen by the hydrogen-consuming device.
