Moisture-driven CO2 pump for direct air capture

Aryl ether-free polymer electrolytes for electrochemical and energy devices

“…In a recent study, Freeman et al investigated DAC using the Fumasep FAA-3 membrane, and a reactive transport model suggested that carbon support rates in AEMs are primarily limited by moisture-swing reaction kinetics. 693 They concluded that polymer design optimization could enhance the moisture-swing effect, or coupling moisture gradient with electrochemical force could lead to more energy-efficient and rapid CO 2 separation.…”
