Abstract
A fuel cell system having a thermally integrated isothermal CO-cleansing subsystem including a water-gas-shift reactor, a preferential oxidation reactor, at least one system heat exchanger, and a closed-loop heat transfer circuit dedicated to that subsystem. The heat transfer circuit utilizes a heat transfer medium which has a high specific heat and is circulated through the circuit at a sufficiently high rate as to thermally dominate the gas stream components communicating with the circuit.
