Warm-up apparatus for fuel evaporator

The present invention relates to a warm-up apparatus for a fuel evaporator. The fuel evaporator (also referred to as a fuel vaporizer) evaporates raw fuel liquid, such as a mixture of methanol and water, and supplies raw fuel gas to a reformer, in which the raw fuel liquid as a raw fuel gas is reformed to produce hydrogen and the produced hydrogen is supplied to a fuel cell. A warm-up apparatus for a fuel evaporator comprises: a catalyst combustor for catalytically burning exhaust gas from a fuel cell to produce combustion gas and supplying the fuel evaporator which evaporates raw fuel liquid with the produced combustion gas as an evaporation heat source; an exhaust gas passage for transferring exhaust gas to the catalyst combustor; and a combustion gas transferring device including a fuel injection portion and a combustion catalyst , and injecting fuel from the fuel injection portion onto the combustion catalyst, where the fuel is catalytically burned to produce combustion gas, and thereafter transferring the produced combustion gas to the catalyst combustor. The combustion gas transferring device is positioned on one side of said exhaust gas passage.
