HYDROGEN GENERATION SYSTEM AND REGULATOR THEREFOR

A passive dual modulating regulator with relative differential venting (“regulator”) for use with a contained hydrogen generation system (“system”) comprises a flexible diaphragm clamped between a first housing section and a second housing section. The regulator defines a hydrogen fluid path in fluid communication with the hydrogen-side of the system, an exterior hydrogen storage vessel, and an exterior of the system. The regulator also defines an oxygen fluid path in fluid communication with the oxygen-side of the system, an exterior oxygen storage vessel, and an exterior of the system. The regulator regulates pressure imbalances between the oxygen-side of the system and the hydrogen-side of the system, and vents oxygen and hydrogen to an exterior of the system to allow collection of both hydrogen and oxygen and avoid rupture of a proton-exchange membrane of the system.
