Fuel cell system with a ventilation line and/or a compressor ventilation line, method for ventilating a housing of a fuel cell system and vehicle

Abstract

The invention relates to a fuel cell system (100) with at least one fuel cell (90), each fuel cell (90) having a cathode inlet (92), and with a housing (50) in which the at least one fuel cell (90) is arranged, the housing (50) having at least one ventilation inlet (52) through which at least one ventilation fluid flows in and at least one outflow outlet (54) through which at least one outflow fluid flows out. The fuel cell system (100) further comprises a supply line (14) to the at least one cathode inlet (92) for providing a supply fluid from a first fluid source to the at least one cathode inlet (14), and a compressor (16) in the supply line (14) for compressing the supply fluid. The fuel cell system (100) also comprises a fluidly communicating ventilation line (24) between the supply line (14) and the at least one ventilation inlet (52) for connecting the supply line (14) to the at least one ventilation line (52), the fluidly communicating ventilation line (24) being connected to the supply line (14) between the compressor (16) and the at least one cathode inlet (92), and/or a compressor cooling line (32) for cooling the compressor (16) and a fluidly communicating compressor ventilation line (34) between the compressor cooling line (32) and the at least one ventilation inlet (52) for connecting the compressor cooling line (32) to the at least one ventilation inlet (52).
