Separating hydrogen from disassociated water

Abstract

In some implementations, a system for disassociating water includes a decomposition chamber, a heating element, a plurality of hollow fiber membranes, and a water inlet. The heating element is positioned in the decomposition chamber and configured to generate heat sufficient to dissociate at least a portion of water to hydrogen and oxygen. The plurality of hollow fiber membranes include at least a section of each hollow fiber membrane that passes through the decomposition chamber and has an inner conduit and an outer wall. The inner conduit for each hollow fiber membrane is configured to pass a sweep gas, and the outer wall for each hollow fiber membrane is configured to selectively pass either oxygen or hydrogen. The water inlet connected to the decomposition chamber and configured to pass water vapor into the decomposition chamber.
