摘要:
A fuel processor and a fuel cell system which have a desulfurizer with multiple sensors, and a method of measuring an adsorbent state in of an adsorbent the desulfurizer The desulfurizer determines the saturation state of the adsorbent using a signal difference between at least two sensors installed adjacent to an inlet and an outlet of the desulfurizer. The desulfurizer provides an accurate determination of the saturation of the adsorbent, and can be used to determine when the adsorbent should be changed. Two desulfurizers can be alternatively used to allow for a consistent fuel flow.
摘要:
A fuel processor having a CO removal unit including an apparatus for warming a CO shifter, is provided. A method of using the fuel processor is also provided. The fuel processor includes a reformer that extracts hydrogen gas from a raw fuel by reacting the raw fuel with water. A burner heats up the reformer to a temperature suitable for extracting the hydrogen gas. A CO shifter removes CO produced during the extraction reaction from the hydrogen gas, and a medium path line in which a heat exchange medium disposed therein absorbs heat from the reformer and passes the heat to the CO shifter. A fuel processor having the above structure can greatly reduce the time required to increases the temperature of the CO shifter to an appropriate operating temperature at an early stage of start up, since a rapid heating of the CO shifter is possible using the heat exchange of steam.

A fuel processor having an improved structure to rapidly increase a temperature of a CO removing unit to an operation temperature, and a method of operating the fuel processor, includes a reformer that produces hydrogen gas by reacting a fuel and water; a CO removing unit that removes CO from the hydrogen produced in the reformer. The CO removing unit comprises a CO shift reactor including a first catalyst that catalyzes a reaction between steam and CO and a second catalyst that catalyzes a reaction between oxygen and CO and between hydrogen and oxygen, and a CO remover including a third catalyst that catalyzes a reaction between oxygen and CO; and an air supply unit that supplies air to the CO shift reactor and the CO remover. The use of the fuel processor can greatly reduce a warming up time required to reach a normal operation of the fuel processor since the CO shift reactor can be rapidly heated using a direct reaction between oxygen and CO and between oxygen and hydrogen during an initial start up operation.
