Abstract

Methods separates a gas comprising providing a first electrode in ion-conducting contact with an electrolyte, providing a second electrode in ion-conducting contact with the electrolyte, wherein the second electrode comprises a liquid metal, providing a displacing material comprising a first surface in contact with the second electrode and a second surface exposed to an environment outside the second electrode, wherein said material permits flow of gas and impedes flow of liquid metal, and establishing a potential between the first and second electrodes, whereby gas flows toward the liquid metal. Other aspects include methods and apparatuses comprising electrodes, electrolytes and displacing materials.
