    摘要： A method and a system meters a supply of methanol and/or water out of a storage reservoir to a fuel-cell system by way of a conveying conduit with a metering valve. A constant mass flow is conveyed out of the storage reservoir into the conveying conduit via a conveying pump. The differential pressure between the conveying conduit and fuel-cell system is set at a predetermined value via a differential-pressure controller which is arranged in a return conduit provided between the conveying conduit and storage reservoir. The methanol and/or water supplied can be set, for example, by varying the opening and closing times of a solenoid valve. A second metering stage can be provided in the return conduit downstream of the first metering stage. When two separate metering systems are used, a common pump motor can be employed.

    摘要： A system to supply hydrogen-rich fuel to an internal combustion engine, whereby a hydrogen-rich gas is produced from a liquid raw fuel by a hydrogen generator. The exhaust line of the internal combustion engine contains an exhaust purification system, such as a DeNOx catalytic converter, which is at least temporarily supplied with hydrogen-rich gas through a bypass line. In addition, the exhaust line is in thermal contact with the hydrogen generator in order to recover thermal energy.

    摘要： The invention provides a process for operating a system for water vapor reforming of methanol in which, in a mixture preparation step, a water vapor/methanol mixture is prepared from water and methanol and is introduced into a reforming reactor. According to the invention, the mixing ratio of the water vapor/methanol mixture is adjusted as a function of the load condition and/or load changes of the system so that a CO-concentration is obtained in the reformate which remains constant over the whole load range.

    摘要： A two-stage evaporator unit converts a liquid reactant mass flow adjustable as a function of a load presetting into a gaseous reactant mass flow. The liquid reactant mass flow is at least partially evaporated in the first stage by a heat-exchange medium, and, if appropriate is completely evaporated and subsequently superheated in the second stage. The evaporator unit is formed by the alternating stacking one on the other of foils having heat-exchange channels and by foils having reaction channels that, in each case, have at least one first and one second stage integrated in one foil. The first stage is configured as a channel with a minimized cross-sectional area which is directly connected to the inflow conduit. The first stage is operated at high coefficients of heat transmission. The total cross-section of the reaction channels in the second stage increases in the flow direction.

    摘要： A process and an apparatus control output of an air-breathing fuel cell system which consists of an air supply line, a fuel cell, an air exhaust line, and a separate gas supply system for hydrogen gas. To control the fuel cell output, an adjustable rotary speed compressor is located in the air supply line and a variable absorption capacity expander is located in the air exhaust line. The compressor, the expander, and an additional electric motor are positioned on a common shaft. The expander converts the pressure energy contained in the exhaust air into mechanical energy and delivers that energy via the common shaft to the compressor. The air volume flow is controlled by the compressor rotary speed and adjusted to a preset value. A preset working pressure is established in the fuel cell system by adjusting the absorption capacity of the expander.
