<P>PROBLEM TO BE SOLVED: To provide a fuel cell system in which a desulfurization unit can be warmed with high energy-efficiency, and to provide a desulfurizer used for the fuel cell system. <P>SOLUTION: The fuel cell system 1 includes a hydrogen generation unit 4 which generates hydrogen-containing gas using hydrogen-containing fuel and cell stack 5 which generates power using the hydrogen containing gas. This fuel cell system is constituted by having: the desulfurization unit 2 which performs desulfurization of the hydrogen-containing fuel supplied to the hydrogen generation unit 4; a heat recovery system which recovers exhaust heat of the cell stack 5 using a heating medium; and a desulfurization system heat exchanging unit 82 by which the heating medium after heat recovery and the desulfurization unit 2 are heat-exchanged with each other. Thereby, the desulfurization unit 2 can be kept warm by being heated using the heating medium. <P>COPYRIGHT: (C)2012,JPO&INPIT |
