  • Patent number: 10094265
    Abstract: A method and device for monitoring the formation of nitrogen dioxide at an oxidation catalytic converter is disclosed. The conversion of the nitrogen oxides, corresponding to a first exhaust gas volume flowrate through the oxidation catalytic converter, is detected. The exhaust gas volume flowrate is then changed and the conversion of the nitrogen oxides which changes with the change in the exhaust gas volume flowrate is also detected. By reference to the respective conversion of the nitrogen oxides at the different exhaust gas flowrates through the oxidation catalytic converter, it is concluded, on the basis of a predetermined relationship between the conversion of the nitrogen oxides and a proportion of nitrogen dioxide in the nitrogen oxides in the exhaust gas, that nitrogen dioxide is being formed at the oxidation catalytic converter.

  • Patent number: 10096850
    Abstract: A method for starting the normal operation of an electrical system with a fuel cell and a transducer from a stop mode is disclosed. The transducer absorbs the electrical power of the fuel cell, in which at least one reactant supply of the fuel cell was interrupted, where the interrupted reactant supply is resumed from a restart signal, and where a fuel cell voltage is prescribed and then regulated by the transducer. The prescribed fuel cell voltage is prescribed in a way that an electrical unloaded fuel cell supplied with reactants will exceed the prescribed fuel cell voltage in every case, and the current of the transducer necessary for maintaining the prescribed fuel cell voltage is measured, where the normal operation is released as of a prescribed current necessary to that effect.
