  • Arrangement comprising a fuel cell system
    Patent number: 9722424
    Abstract: A system (0) includes an electrical load system (54) with a load network battery (82), and a fuel cell system (1). Operation is simplified, especially during start of the fuel cell system (1) if the fuel cell system (1) has a system battery (56). A system voltage across the system battery (56) can be supplied to electrical system loads (80) of the fuel cell system (1) and, via a load voltage converter (77) and at least one additional voltage converter (86), to the load system (54) and secondary electrical loads (84, 85).
    Type: Grant
    Filed: July 9, 2012
    Date of Patent: August 1, 2017
    Assignee: Eberspächer Climate Control Systems GmbH & Co. KG
    Inventors: Andreas Kaupert, Valentin Notemann, Karsten Reiners, Markus Willkommen

  • Fuel cell system and operating process
    Patent number: 8563184
    Abstract: A fuel cell system (1), especially in a motor vehicle, is provided with a fuel cell (2), which generates electric current during the operation from anode gas and cathode gas, with a residual gas burner (3), which reacts anode waste gas with cathode waste gas into burner waste gas during the operation; with an air delivery device (17), which feeds air as cathode gas to the fuel cell (2) via a fuel cell air line (12) during the operation; and with a first heat exchanger (14), which couples a waste gas line (13) removing burner waste gas from the residual gas burner (3) with the fuel cell air line (12) in a heat-transmitting operation.
