Abstract
An electrochemical cell has a cell assembly that has an anode, an air cathode infused with a liquid electrolyte, an ionically-conductive separator medium disposed between and coupling said anode and said air cathode, a housing enclosing said anode, said cathode, and said ionically-conductive separator medium, and a mixture of oxygen and carbon dioxide disposed within said housing in gaseous communication with said air cathode, wherein said carbon dioxide comprises from about 0.04% to about 95% molar fraction of said mixture of oxygen and carbon dioxide.
Claims25
An electrochemical cell comprising:
- an anode,
- an air cathode infused with a liquid electrolyte,
- an ionically-conductive separator medium disposed between and coupling said anode and said air cathode,
- a housing enclosing said anode, said cathode, and said ionically-conductive separator medium, and
- a mixture of oxygen and carbon dioxide disposed within said housing in gaseous communication with said air cathode;
- wherein said carbon dioxide comprises from about 0.04% to about 95% molar fraction of said mixture of oxygen and carbon dioxide.
A method for operating an electrochemical cell comprising:
- providing an enclosed cell assembly comprising
- an anode,
- an air cathode having a liquid electrolyte infused therein,
- an ionically-conductive separator medium disposed between and coupling said anode and said air cathode,
- a housing enclosing said anode, said air cathode, said ionically-conductive separator medium;
- and
- selectively providing a mixture of oxygen and carbon dioxide to an interior of said housing so as to be in gaseous communication with said air cathode;
- wherein said carbon dioxide comprises from about 0.04% to about 95% molar fraction of said mixture of oxygen and carbon dioxide.
