Separating hydrogen from disassociated water

摘要

In some implementations, a system for producing hydrogen and oxygen from water includes a target, an oxygen selective membrane, a cooling chamber, and a hydrogen selective membrane. The target heats to at least a temperature that thermally decomposes water, receives water vapor, heats the received water vapor to the temperature that thermally decomposes water to form a heated vapor, and passes the heated vapor to an oxygen selective membrane. The oxygen selective membrane separates, at or near the temperature that thermally decomposes water, oxygen from the heated vapor to form a hydrogen-rich vapor. The cooling chamber cools the hydrogen-rich vapor to at least a specified temperature. The hydrogen selective membrane separates hydrogen in the hydrogen-rich vapor to leave substantially water vapor.

1. A system for producing hydrogen and oxygen from water, comprising:
a target that heats to at least a temperature that thermally decomposes water, receives water vapor, heats the received water vapor to the temperature that thermally decomposes water to form a heated vapor, and passes the heated vapor to an oxygen selective membrane, wherein the target includes an oxide-based refractory material mixed with a dark-colored metal oxide; the oxygen selective membrane that, at or near the temperature that thermally decomposes water, separates oxygen from the heated vapor to form a hydrogen-rich vapor; a cooling chamber that cools the hydrogen-rich vapor to at least a specified temperature; and a hydrogen selective membrane that separates hydrogen in the hydrogen-rich vapor to leave substantially water vapor.
