NOVELTY - The hydrogen generator comprises a pressurized chamber having a hydrogen-containing material (113) disposed in the chamber, a first fluidic pathway including an upstream portion, which is upstream of the chamber and a downstream portion, which is downstream of the chamber, a second fluidic pathway adjoined to the downstream portion of the first fluidic pathway, a first reservoir (103) containing the liquid medium and having first and second sub-reservoirs, an inlet present in fluidic communication with the first and second sub-reservoirs, and a second reservoir (105).    USE - The hydrogen generator is useful in fuel cells, laptop computers, handheld electronic devices and combustion engines.    ADVANTAGE - The hydrogen generator is lightweight, smaller in size and flexible, has high strength and relative chemical inertness, prevents or reduces the emission of hydrogen gas from the device, and produces the hydrogen gas at ambient conditions with high yield and improved and efficient performance.    DETAILED DESCRIPTION - The hydrogen generator comprises a pressurized chamber having a hydrogen-containing material (113) disposed in the chamber, a first fluidic pathway including an upstream portion, which is upstream of the chamber and a downstream portion, which is downstream of the chamber, a second fluidic pathway adjoined to the downstream portion of the first fluidic pathway, a first reservoir (103) containing the liquid medium and having first and second sub-reservoirs, an inlet present in fluidic communication with the first and second sub-reservoirs, a second reservoir (105) containing a hydrogen-containing material, and a third fluidic pathway connecting the first reservoir to the second fluidic pathway at a point downstream from the chamber. The first and second fluidic pathways contain a liquid medium (119) in which the hydrogen-containing material is soluble. The reservoir is present in fluidic communication with each of the first and second fluidic pathways. The chamber comprises an elastomeric material. The first reservoir is present in fluidic communication with both of the first and second fluidic pathways. Each of the first and second sub-reservoirs comprises a portion of the liquid medium disposed within an elastomeric chamber, and comprises an elastomeric tube. The first and second sub-reservoirs are charged with the liquid medium. The chamber is disposed within a second reservoir. The pressure inside of the first and second reservoirs is equal. The hydrogen generator further comprises a catalytic reactor present in fluidic communication with the first and second fluidic pathways downstream from the point at which the first and second fluidic pathways are adjoined, a catalytic hydrogen recombiner adapted to convert hydrogen gas to water in the presence of oxygen, and a regulator adapted to control the flow of fluid into the first fluidic pathway and second fluidic pathway. The second reservoir is present in fluidic communication with the first reservoir by the way of a first fluidic pathway. The concentration of the hydrogen-containing material in the liquid medium is lower immediately downstream from the point at which the first and second fluidic pathways are adjoined upstream from the catalytic reactor. The second fluidic pathway is present in fluidic communication with the first reservoir and in fluidic communication with the first fluidic pathway at a point downstream from the second reservoir. The catalytic reactor is present in fluidic communication with a byproduct receptacle disposed within the first reservoir. The byproduct receptacle comprises a hydrogen permeable material. The hydrogen recombiner is present in fluidic communication with the first reservoir by the way of a pressure activated valve. The regulator comprises an actuator whose movement is controlled by first and second opposing springs. An INDEPENDENT CLAIM is included for a method for generating hydrogen gas.
