  • Fuel cell system with a vibration generator, and method for operating a fuel cell system with a vibration generator
    Patent number: 11777116
    Abstract: A fuel cell system (200), wherein the fuel cell system (200) has: a) a fuel cell stack (10), b) an anode gas path (20) which fluidically communicates with the fuel cell stack (10) and which serves for supplying anode gas from an anode gas store (22) to the fuel cell stack (10), c) a cathode gas path (30) which fluidically communicates with the fuel cell stack (10) and which serves for supplying cathode gas from a cathode gas store (32) to the fuel cell stack (10), d) a cooling fluid path (40) which fluidically communicates with the fuel cell stack (10) and which serves for supplying cooling fluid from a cooling fluid store (42) to the fuel cell stack (10), e) a vibration generator (60) which is in data-transmitting communication with a control unit (50) and which serves for setting the fuel cell stack (10) into a vibrating state, and f) the control unit (50) for actuating the vibration generator (60) in order to set the fuel cell stack (10) into the vibrating state by means of the vibration generator (60).

  • Fuel cell stack, method for producing a fuel cell stack and method for operating a fuel cell stack
    Patent number: 11652229
    Abstract: The present invention relates to a fuel cell stack (10) and to a method for producing such a fuel cell stack (10). The fuel cell stack (10) comprises at least two fuel cell modules (58) with in each case at least two individual cells (5), each fuel cell module (58) having module end plates (70) on both cell stack outer sides (66), and fuel cell stack compression means (82), via which the fuel cell modules (58) stacked one on top of the other are braced to form a fuel cell stack (10).
