Abstract
Disclosed herein is an air-water extraction system that includes a water selective membrane configured to transport water from humid air via selective diffusion through the water selective membrane; a low pressure chamber in fluid communication with the water selective membrane and a hydrogen gas inlet configured to deliver a dry hydrogen to the low pressure gas chamber, a membrane and electrode assembly comprising an anode, a proton exchange membrane, a cathode, and a power supply; wherein the anode is in fluid communication with the low pressure chamber, a high pressure chamber in fluid communication with the cathode for receiving a saturated hydrogen and a liquid water from the cathode; a water conduit in fluid communication with the high pressure chamber configured to remove the liquid water from the high pressure chamber, and a hydrogen conduit for removing the saturated hydrogen from the high pressure chamber.
