  • Patent number: 10847817
    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.

  • Patent number: 10790495
    Abstract: A battery pack includes a two-dimensional or three-dimensional array of battery cells, each cell having a polygonal (i.e, rectangular) shape and a “three side-and-one side” terminal configuration. In some embodiments, the terminal configuration allows the cells to be electrically connected in any configuration, series, parallel, or series parallel simply by changing the orientation of the cell relative to adjacent cells and applying pressure to maintain contact. For a rectangular cell shape, this is achieved by providing three like charged terminals (such as positive) on three respective sides of the cell and one oppositely charged terminal (such as negative) on a fourth side of the cell while maintaining a neutral charge on both of the end surfaces of the cell.
