Abstract: The invention relates to a method to determine a content of a gas component in a gas mixture delivered recirculating through an anode chamber (12) or a cathode chamber (13) of a fuel cell (10), wherein the delivery takes place via a delivery device (26) functioning according to the positive displacement principle. The invention also relates to a fuel cell system (100) configured to execute the method. According to the invention, the content of the gas component is determined depending on geometric parameters (V, ?) and operating parameters (n, U, I) of the delivery device (26), as well as on thermodynamic state variables (p, T) of the gas mixture. The sought target quantity, for example a hydrogen component of an anode gas, can thus be determined in a simple and robust manner from quantities that are already known or measured.

Abstract: An area coverage, which is carried out by a volume of printing ink transferred to a print stock by an inking unit of a printing press, can be adjusted. An ink feed to the inking unit can be disengaged in zones or can be interrupted in the inking and upon reaching of a final phase of a printing process which was previously carried out by the printing press. The volume of printing ink remaining on the print stock after such a disengagement or interruption in the ink feed in the inking unit in the final phase of the printing process previously carried out by the printing press, is transferred to the print stock until the area coverage made by the volume of printing ink transferred to the print stock equals a specified target value of area coverage for an impression of a subsequent printing process. A corresponding method is also provided for execution in a printing press that has a plurality of printing units.
