Abstract
An apparatus and method purify hydrogen from a mixed fluid containing gaseous hydrogen, gaseous oxygen, and liquid water. The apparatus has a mixed fluid channel through which the mixed fluid flows; a first gas channel through which a mixed gas containing gaseous hydrogen and gaseous oxygen flows; a second gas channel through which gaseous hydrogen or oxygen flows; a gas-liquid separating membrane forming a wall between the mixed fluid channel and the first gas channel, separating the mixed gas from the mixed fluid of the mixed fluid channel, and providing the separated mixed gas to the first gas channel; and a hydrogen or oxygen separating membrane forming a wall between the first gas channel and the second gas channel, separating gaseous hydrogen or oxygen from the mixed gas of the first gas channel, and providing the separated gaseous hydrogen or oxygen to the second gas channel.
