2. A process for separating hydrogen and oxygen comprising:
providing a gas mixture feed comprising oxygen and hydrogen;
passing the gas mixture feed through an adsorption medium that selectively adsorbs hydrogen from the gas mixture feed producing a hydrogen enriched adsorption medium;
desorbing the adsorbed hydrogen by exposing the hydrogen enriched adsorption medium to a vacuum forming a hydrogen enriched purge gas and a regenerated adsorption medium, and
injecting a hydrogen product gas to the gas mixture feed.
