The present disclosure relates generally to devices, systems, and methods for separating target species (eg, CO 2 ) from gas mixtures (eg, gas streams) by electrochemical processes. The gas separation system may include a plurality of electrochemical cells in fluid communication with the gas inlet and the gas outlet, wherein each of the plurality of electrochemical cells is a first porous negative electrode, each including a first electroactive species. And a second porous negative electrode, a positive electrode containing a second electroactive species, a first separator located between the first porous negative electrode and the positive electrode, a second porous negative electrode and a positive electrode And a second separator located therebetween. |
