Abstract: A fuel processor includes a reformer that generates hydrogen gas by reacting a fuel source and water; a burner that heats the reformer to a temperature suitable for a hydrogen generation reaction; a CO shift reactor that removes CO generated during the hydrogen generation reaction in the reformer; a heating element for heating the CO shift reactor; and a cooling element for cooling the CO shift reactor, wherein the cooling element comprises at least one of a cooling water flow line for heat exchange with the CO shift reactor when cooling water flows through the cooling water flow line and a cooling gas flow line for heat exchange with the CO shift reactor when a cooling gas, which is a burner exhaust gas that has heat exchanged with cooling water, flows through the cooling gas flow line. When the fuel processor is operated, a stable CO removal performance can be maintained since the temperature of the CO shift reactor can be actively controlled.
