NOVELTY - The car comprises an internal-combustion engine (51), a reformer (3) for generating a hydrogen-containing reformate gas, a liquid fuel tank (39), a reformer-fuel pipe (17) guiding from the fuel tank to the reformer, a line (19) for supplying the fuel to the reformer, an engine conveyer for propelling fuel to the engine, and a reformer-surge chamber and an engine-surge chamber connected with the fuel tank. The supply-line is arranged in the fuel tank and attached to the fuel pipe. The engine conveyer is arranged in the fuel tank and an engine fuel pipe (46) is attached at the engine conveyer.    USE - Used as a car.    ADVANTAGE - The car has improved function by a homogeneous air/fuel mixture in the reformer, which prevents bubble formation in the fuel.    DETAILED DESCRIPTION - The car comprises an internal-combustion engine (51), a reformer (3) for generating a hydrogen-containing reformate gas, a liquid fuel tank (39), a reformer-fuel pipe (17) guiding from the fuel tank to the reformer, a line (19) for supplying the fuel to the reformer, an engine conveyer for propelling fuel to the engine, and a reformer-surge chamber and an engine-surge chamber connected with the fuel tank. The supply-line is arranged in the fuel tank and attached to the fuel pipe. The engine conveyer is arranged in the fuel tank and an engine fuel pipe (46) is attached at the engine conveyer. The reformer supply line is arranged in the reformer-surge chamber. The engine conveyer is arranged in the engine-surge chamber. The both surge chamber are aligned one on the other so that the communicating connection between the reformer-surge chamber and the fuel tank is interrupted from a pre-determined threshold value in the removing fuel level, while retaining the communicating connection between the engine-surge chamber and the fuel tank. A gas cell system is intended and comprises the reformer and a gas cell for generating electric current using reformate gas generated from the reformer. The reformer comprises a liquid-fuel evaporator. A metering valve is arranged in the reformer fuel-pipe and/or a pressure valve is arranged in a return line from the reformer fuel pipe to the fuel tank. A non-return check valve and/or a check valve are arranged in the reformer fuel pipe. A pressure sensor and/or a temperature sensor are arranged in the return line. A level measuring instrument is attached to the fuel tank and/or the reformer-surge chamber. An INDEPENDENT CLAIM is included for a reformer for generating hydrogen-containing reformate gas for a gas cell system in a motor vehicle.
