1. A contained hydrogen generation system (“system”) comprising:
a high-pressure containment vessel (“vessel”) having at least one sidewall and a floor, the vessel having an exterior surface and an interior surface that at least partially defines a hydrogen plenum;
a cover opposite the floor and coupled to the at least one sidewall of the vessel, the cover defining an upper and a lower surface and having a plurality of high-pressure fittings thereon;
one or more proton-exchange membrane (PEM) cells disposed in the hydrogen plenum;
an oxygen-water separator disposed in the hydrogen plenum, the oxygen-water separator receives and stores water from an exterior of the vessel, supplies water to the one or more PEM cells, and receives oxygenated water from an anode-side of the one or more PEM cells, the oxygen-water separator includes an oxygen outlet line; and
a passive dual regulator with relative differential venting (regulator) disposed in the hydrogen plenum, the regulator including:
a hydrogen fluid path in fluid communication with the hydrogen plenum, an exterior hydrogen storage vessel, and an exterior of the vessel; and
an oxygen fluid path in fluid communication with the oxygen outlet line of the oxygen-water separator, an exterior oxygen storage vessel, and an exterior of the vessel;
wherein the regulator regulates pressure imbalances between an oxygen-side of the system and a hydrogen-side of the system, and vents oxygen and hydrogen to an exterior of the vessel to allow collection of both hydrogen and oxygen and avoid rupture of a PEM in the one or more PEM cells.
