Claim 30:
31. A gas separation system, comprising a plurality of electrochemical cells in fluid communication with a gas inlet and a gas outlet, wherein each of the plurality of electrochemical cells comprises:
a first electrode comprising an electroactive species in a reduced state, wherein the electroactive species comprises an oxidized state and at least one reduced state which bonds with the Lewis acid gas to form the anion adduct;
a second electrode comprising a complementary electroactive layer;
a first separator between the first electrode and the second electrode; and
a non-aqueous electrolyte comprising a stabilizing additive, wherein the stabilizing additive comprises a cationic Lewis acid, a hydrogen-bond donor, or a combination thereof,
wherein the stabilizing additive is present in an effective amount to:
kinetically favor the forming of the anion adduct from the reduced electroactive species and the Lewis acid gas,
thermodynamically favor the forming of the anion adduct in a thermodynamic equilibrium between the anion adduct and the reduced electroactive species, or
kinetically favor the forming of the anion adduct from the reduced electroactive species and thermodynamically favor the forming of the anion adduct in the thermodynamic equilibrium between the anion adduct and the reduced electroactive species.
