Assignee: FUELCELL ENERGY, INC
Field: Chemical engineering (Chemistry)
Classification: CPC H  B  Y | IPC B  H

Claim 0:
1. A fuel cell system comprising:
a first fuel cell comprising 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 comprising:
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 CO2.
