PURPOSE: Provided is a simplified but highly efficient fuel cell system, permitting to perform the flame off detection and so on without supplying the burner with additional raw fuel, even if a flame rod system flame detection means is adopted as burner for reformer. CONSTITUTION: The fuel cell system comprises a reformer for reforming a hydrocarbon base fuel into hydrogen, a CO transformer for transforming carbon monoxide, a CO eliminator for removing carbon monoxide, a fuel cell for generating electricity from hydrogen, and a burner for the reformer for burning hydrogen gas discharged from the fuel cell and supplying the reformer with heat necessary for reforming reaction, wherein the burner for the reformer is provided with a flame rod system flame detection means and, at the same time, supplied with hydrogen gas containing a flame detectable amount of fuel gas. The fuel cell system comprises a reformer for reforming a hydrocarbon base fuel into hydrogen, a CO transformer for transforming carbon monoxide, a CO eliminator for removing carbon monoxide, a burner for burning hydrogen for exhaust heat recovery without supplying with the hydrogen to the fuel cell until each reactor stabilizes during a start or stop, a fuel cell for generating electricity from hydrogen, and a burner for the reformer for burning hydrogen gas discharged from the fuel cell and supplying the reformer with heat necessary for reforming reaction, wherein the each burner is provided with a flame rod system flame detection means and, at the same time, supplied with hydrogen gas containing a flame detectable amount of fuel gas. |
