<P>PROBLEM TO BE SOLVED: To provide a fuel cell system doing away with a dedicated heating device to heat fuel gas and oxidizing gas for quick start-up of a fuel cell. <P>SOLUTION: (1) The fuel cell system is equipped with a fuel cell 10, a supply path 11 of fuel gas and oxidizing gas to the fuel cell, an exhaust path 12 of the fuel gas and the oxidizing gas from the fuel cell and a reactor 13 provided at the exhaust path 12 for oxidizing fuel offgas from the fuel cell. The system is also provided with a bypass path 14 going from the supply path 11 for the fuel cell to the reactor 13 and returning from the reactor 13 to the supply path of the fuel cell, and, when the fuel cell is started, at least part of the fuel gas and the oxidizing gas supplied to the fuel cell is carried through in the bypass path 14 to heat with the reactor 13. (2) The bypass path 14 is communicated with an inside of the reactor 13, so that gas is to be further heated and moisturized by reaction at the reactor 13 when the fuel cell is started. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
