PROBLEM TO BE SOLVED: To operate a fuel cell system while removing a sulphur compound-containing gas in a fuel gas, e.g., city gas, efficiently.SOLUTION: After fuel gas is passed through an adsorber 1 and sulphur compounds are removed therefrom, the fuel gas is modified and supplied to a fuel cell stack 3. The adsorber 1 is provided with a hot water jacket 1a, and hot wastewater from the water cooling mechanism 3a of the stack 3 is distributed to the jacket 1a, thus heating the inside of the adsorber 1 to 60-85°C. The jacket outflow water from the jacket 1a is returned back to the water cooling mechanism 3a of the stack 3 via the heat source fluid side of a heat exchanger 6. |
