A fuel cell system is provided to increase the thermal efficiency of a burner, to reduce the consumption of fuel supplied to the burner, and to improve the quality of a fuel cell. A fuel cell system comprises: a stack unit for generating electricity via electrochemical reactions between hydrogen and oxygen; a reformer unit for supplying hydrogen to the stack unit; and an air supplying unit for supplying air to the stack unit, wherein the off-gas discharged from the stack unit is supplied to the burner(270) of the reformer unit, the burner including a burner body(271), a catalytic section(273) disposed at the center of the burner body, and metal fibers(275) filled in the gap between the burner body and the catalytic section. |
