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.
