DESULFURIZATION APPARATUS AND FUEL CELL SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a desulfurization apparatus suppressing the degradation of reliability or durability of a desulfurizer, and to provide a fuel cell system.

SOLUTION: The desulfurization apparatus 3 includes: a desulfurizer 7 that houses a desulfurization catalyst 7a for removing a sulfur content from a liquid fuel to be supplied to a reformer 5 that generates a reformed gas containing hydrogen; a heater 8 heating the desulfurization catalyst 7a; a pressure meter 14 for measuring the pressure of a liquid fuel in the desulfurizer 7; and a control unit 15 controlling the heater 8. The control unit 15 controls the heater 8 based on the pressure measured by the pressure meter 14 in such a manner that the pressure of the liquid fuel in the desulfurizer 7 is kept at a predetermined pressure equal to or lower than the withstand pressure of the desulfurizer 7.
