  • Fuel cell system and method for operating such a system
    Patent number: 10290887
    Abstract: A fuel cell system (100), including a fuel cell (10), which has a cathode input (25) and a cathode output (27); a cathode supply path (24) situated upstream from the cathode input (25) and connected thereto; a cathode exhaust gas path (26) situated downstream from the cathode output (27) and connected thereto; a conveying means (32) situated in the cathode supply path (24) for conveying a cathode gas flow (GS_K) into the cathode input (25) and/or an adjustable exhaust gas throttle means (36), situated in the cathode exhaust gas path (26), for influencing a flow resistance of the cathode exhaust gas path (26); and a regulating device (46), configured to regulate the cathode gas flow (GS_K) and/or a cathode pressure (p_K) is provided. Also, a method (999) for operating a fuel cell system (100) of this type is provided.
