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.
