MOLTEN CARBONATE FUEL CELL ANODE EXHAUST POST-PROCESSING FOR CARBON DIOXIDE CAPTURE

Last updated:

Abstract:

A fuel cell system includes: a first fuel cell including a first anode and a first cathode, wherein the first anode is configured to output a first anode exhaust gas; a first oxidizer configured to receive the first anode exhaust gas and air from a first air supply, to react the first anode exhaust gas and the air in a preferential oxidation reaction, and to output an oxidized gas; a second fuel cell configured to act as an electrochemical hydrogen separator, the second fuel cell including: a second anode configured to receive the oxidized gas from the first oxidizer and to output a second anode exhaust gas, and a second cathode configured to output a hydrogen stream; and a condenser configured to receive the second anode exhaust gas and to separate water and CO.sub.2.
