  • Publication number: 20200374659
    Abstract: An address allocation method, in which coordinate data is ascertained by a coordinate device, the data characterizing a two-dimensional position of a demarcated location, and in which the ascertained coordinate data is allocated to a sequence of words having at least several words by an allocation device. Elevation data is ascertained by an elevation determination device which characterizes an elevation of the demarcated location relative to a predetermined normal elevation. The sequence of words is adjusted by the allocation device depending on the ascertained elevation data. The sequence of words unambiguously characterizes the coordinate data and the elevation data.

  • Patent number: 10115986
    Abstract: A method for changing a fuel cell system from a normal mode of operation over to a standby mode comprises the following steps: a) reducing the load withdrawal—via the electric circuit of the fuel cell stack—down to a load within the range from ?1% to +5% around a load with an optimal system efficiency, b) regulating down the anode pressure down via the anode supply system, c) in the meantime, maintaining and controlling the cathode gas feed via the cathode supply system so that the pressure differential between the anode spaces and the cathode spaces does not exceed a prescribed maximum pressure differential, d) switching off the cathode gas feed if the pressure differential between the anode spaces and of the fuel cell stack and the environment has reached the prescribed maximum pressure differential, and e) switching off the load withdrawal via the external electric circuit at the latest when a prescribed minimum limit voltage of the fuel cell stack has been reached.
