Abstract: This invention relates to a synthetic method for the preparation of Compound 1 and precursors thereof. Compound 1 is prepared via reaction of isoxazole 2 with phenylether (R)-3-ONa.

Abstract: A method is used to start up a fuel cell electrically in a fuel cell installation, especially a fuel cell for use in a motor vehicle, with a gas-generating system producing a hydrogen-containing gas flow. The gas flow from the gas-generating system and an oxygen-containing gas flow are brought together and combusted after the fuel cell. The fuel cell is started up electrically as a function of a temperature course existing in the region of combustion of the gas flows.

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 generating system for a fuel cell system as well as to a method of operating same. In order to provide hydrogen-containing combustible gas as rapidly as possible and to reduce the exhaust gas emissions, for the start of the operation of the gas generating system, at least one catalytic burner is started and the generated heat is used for evaporating a combustion agent and/or water and for the heating-up of an additionally connected partial reforming unit or partial oxidation stage in order to generate a hydrogen-containing gas for the fuel cell unit by reforming or partial oxidation.

Abstract: In a method and apparatus for producing a hydrogenous gas stream for a fuel cell system, the share of CO contained in the gas stream, is reduced by providing one or more selective oxidation stages which preferably are thermally coupled to a reformer for the reforming of hydrocarbons, or to a heat exchanger. In order to supply the fuel cell system, as quickly as possible, with a hydrogenous gas stream having a low share of CO, so that it can be placed in operation at the temperature of the surrounding environment, one or more additional, thermally decoupled, selective oxidation stages is series-connected to the existing selective oxidation stages at the beginning or end of the series, or at intermediate points.

Abstract: A method for operating a gas-generation device, which comprises a partial oxidation reactor with a downstream steam reformer, includes in order to start the gas-generation device, a quantity of air in all the operating phases is set in such a way that oxygen levels in the partial oxidation product gas caused by unburnt air constituents are minimized. Furthermore, an adiabatic, catalytic after-treatment stage, in which oxygen constituents of the partial oxidation product gas are converted, is connected between the partial oxidation reactor and the steam reformer.
