NOVELTY - A hydrogen-containing gas producing device comprises evaporator, high temperature reformer, and burner. The evaporator evaporates the feed material. The reformer performs a steam reforming the superheated feed material. The burner provides thermal energy required for steam reforming by burning a gas stream produced in the steam reforming by burning a gas stream that contains fuel and oxygen.    USE - For producing hydrogen-containing gas for fuel cell system for motor vehicle (claimed).    ADVANTAGE - The device possess simple design, can process various types of fuels (particularly various alcohols), in not affected by contamination with long-chain hydrocarbon compounds in the fuel, and/or which offers good cold starting characteristics.    DETAILED DESCRIPTION - A hydrogen-containing gas producing device comprises evaporator (2), superheater (4), high temperature reformer (6), burner (22), water gas shift stage (9), and cooler. The evaporator for evaporating the feed material comprising water and hydrocarbon-containing substance, to yield a vapor. The vapor is superheated to form a superheated feed material, which is subjected to steam reforming in the high temperature reformer. The burner provides thermal energy required for steam reforming by burning a gas stream produced in the steam reforming by burning a gas stream that contains fuel and oxygen. The water gas shift state reduces the carbon monoxide content of reformate stream produced in the steam reforming. The cooler reduces the temperature of reformate stream between the point where the reformate stream is discharged out of the high temperature reformer and the point where the reformate stream enters the water gas shift stage.    An INDEPENDENT CLAIM is also included for a method for producing hydrogen-containing gas from a feed material for a fuel cell system, comprising evaporating the feed material to yield a vapor, superheating the vapor, subjecting to steam reforming the provided superheated feed material, and reducing the carbon monoxide content of the cooled stream by a water gas shift reaction.    DESCRIPTION OF DRAWING(S) - The figure is a schematic view of the inventive device.    Evaporator (2)    Superheater (4)    High temperature reformer (6)    Water gas shift stage (9)    Burner (22)
