Abstract: An apparatus for the selective catalytic oxidation of carbon monoxide contained in a hydrogen-rich mixed gas flow, includes a reaction chamber filled with a catalyst and a cooling chamber through which a coolant flows formed between successive plates. The plates have openings that form inlet and outlet channels for the mixed gas flow and the coolant. An oxidizing gas is supplied directly into the inlet channel for the mixed gas flow. For two-stage apparatuses, a separating plate without an opening for the inlet channel for the mixed gas flow is arranged between the first and the second stage, and an apparatus for supplying the oxidizing gas to the second stage is passed into the outlet channel for the mixed gas flow from the first stage.

Abstract: 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.

Abstract: An apparatus for supplying fuel to a gas-generating system to generate hydrogen-rich gas in a fuel cell system includes two gas-generating components; a metering device, which can supply fuel by a valve-controlled distribution to each of the two gas-generating components; and a fuel storage basin. The fuel basin which supplies fuel to one of the gas-generating components during a changeover or connecting process between the gas-generating components.

Abstract: A gas generation system for providing a gas flow to be supplied to a reformer includes an evaporator for evaporating the components contained in a gas flow, wherein the gas flow includes at least one carbon compound, such as hydrocarbon or alcohol, and water vapor. A normalizing stage is connected between the evaporator and the reformer for equalizing the temperature distribution in the gas flow to be supplied to the reformer. The temperature of the gas flow should be equalized to a temperature range below the maximum allowable reformer inlet temperature. In this way, temperature maxima caused by a load change are equalized, thereby significantly increasing the service life of the reformer catalyst.
Abstract: A device feeds educts to parallel spaces separated from one another by way of a distributor unit. Outlets of the distributor unit are assigned to the spaces, and evaporator structures for the evaporation of liquid media are provided in the spaces. Each outlet of the distributor unit project into a space. The boiling point of the medium in the distributor unit is maintained above the temperature of the medium in the distributor unit.
