In this article, the authors demonstrate an electrochemically driven CO₂ separator (EDCS) to remove CO₂ from the air feed using a shorted membrane that conducts both anions and electrons. They show that a 25 cm² shorted membrane EDCS can achieve >99% CO₂ removal from 2,000 standard cubic centimetres per minute (sccm) of air for 450 hours and operate effectively under load-following dynamic conditions.
