Abstract
An electrochemical module (EM) transfers a fluid across a membrane thereof using oxygen as a carrier gas. The EM has an anion exchange membrane (AEM) disposed between a first and second electrodes, each of which includes a catalyst. At an inlet side, the catalyst facilitates reaction of the fluid with carrier gas, such that an anion is formed. The anion is transported across the AEM in the presence of an electric field applied to the electrodes. At an outlet side, the catalyst facilitates dissociation of the anion back to the fluid and carrier gas. In some embodiments, the fluid comprises carbon dioxide, and the transporting by the EM is part of a heating/cooling cycle or a power generation cycle, or is used to capture carbon dioxide for storage or regeneration of stale air. In some embodiments, the fluid comprises water vapor, and the transporting by the EM dehumidifies air.
