Claim 8:
9. The method of claim 7, further comprising:
at a first heat exchanger, cooling the first anode exhaust gas and outputting a first partially-cooled gas;
at a first CO shift reactor, performing a first CO shift reaction at a first temperature on the first partially-cooled gas and outputting a first shifted gas;
at a second heat exchanger, cooling the first shifted gas and outputting a second partially-cooled gas;
at a second CO shift reactor, performing a second CO shift reaction at a second temperature on the second partially-cooled gas and outputting a second shifted gas; and
at a third heat exchanger, cooling the second shifted gas and outputting a cooled gas;
wherein the first anode exhaust gas received at the first oxidizer is the cooled gas output from the third heat exchanger; and
wherein the first temperature is higher than the second temperature.
