MUMBAI, India, July 5 -- Intellectual Property India has published a patent application (202517058631 A) filed by Robert Bosch Gmbh, Stuttgart, Germany, on June 18, for 'method for determining information of a fuel cell stack after a switch-off, and vehicle.'
Inventor(s) include Marino, Michael Giuseppe; Wessner, Jochen; Gerling, Christophe; Berner, Ulrich; Hackenberg, Juergen; and Sauter, Ulrich.
The application for the patent was published on July 4, under issue no. 27/2025.
According to the abstract released by the Intellectual Property India: "The invention relates to a method for determining information about a fuel cell stack (100) of a vehicle (200) after a switch-off. The method comprises as one step, detecting (320) a switch-off command, and as a step, closing (341) a cathode gas inlet value and closing (342) a cathode gas outlet valve in order to fluidically block off a cathode region (K). The method furthermore comprises, as one step, applying (360) an electrical load device (230) to the fuel cell stack (100) until a predefined target voltage is detected (370), and as a step, closing (381) an anode gas inlet value and closing (382) an anode gas outlet valve in order to fluidically block off an anode region (A). The method further comprises, as a step, applying (400) an electrical measurement signal to the fuel cell stack (100), and as a further step, detecting (420) a signal response. The method further comprises, as one step, determining (440) information at least about the at least one stack part of the fuel cell stack (100) of the fuel cell system (210) based on the applied measurement signal and the detected signal response."
The patent application was internationally filed on Dec. 15, 2023, under International application No.PCT/EP2023/086074.
