    摘要: A fuel cell system 1 comprises a fuel cell stack 10, an evaporator 21, a reforming device 22, a supercharger 23, an offgas heating device 24, and a catalytic combustion chamber 25. Offgas exhausted from the fuel cell stack 10 is burnt in the catalytic combustion chamber 25, and the burnt offgas is introduced to the evaporator 21 to be heat exchanged with a reforming raw fuel and reforming air. The burnt offgas cooled by means of the heat exchange is introduced to the offgas heating device 24, to be used as a heat source for heating the offgas exhausted from the fuel cell stack 10. The offgas can be heated by the burnt offgas, and the moisture in the offgas can be vaporized and introduced to the catalytic combustion chamber 25.

    摘要: A vaporizer generates vapor by vaporizing a liquid. In particular, a vaporizer generates fuel vapor that is used for reforming fuel by vaporizing a liquid fuel that contains a hydrocarbon. This vaporizer includes a heating gas direct movement flow path along which a heating gas flows by moving directly in a horizontal direction; vaporization flow paths that are positioned such that they can exchange heat with the heating gas direct movement flow path, and that vaporizes liquid fuel; a fuel supply pipe that supplies the liquid fuel to the vaporization flow paths; and a vapor flow path that is positioned in an upstream portion on the heating gas direct movement flow path from the vaporization flow paths and that heat fuel vapor that is discharged from the vaporization flow paths. Fuel vapor that is generated on the vaporization flow paths circulates upwards in the direction of gravity along the vaporization flow paths, and subsequently is discharged from a top portion of the vaporization flow paths and is introduced into the vapor flow path. The fuel vapor then circulates in the direction of gravity along the vapor flow path.

    摘要: Air for reforming used in the reformation reaction in a reformer 3 of a fuel cell system FCS is supplied into an evaporator 2. In the evaporator 2, raw fuel liquid is evaporated to produce raw fuel gas. The reforming air and the raw fuel gas are well admixed within the evaporator 2 and a conduit 8C connecting the evaporator 2 to the reformer 3. At the starting of the fuel cell system FCS, a large amount of the air is introduced into the evaporator 2 via an air inlet port 14B for starting. The fuel cell system having such a configuration can appropriately mix the fuel gas in the reformer with the reforming air and can rapidly operate the evaporator and the reformer at the time of starting without enlarging the total size of the fuel cell system.
