DEVICE FOR HUMIDIFYING ANODE GAS

摘要

The invention relates to a device for humidifying an anode chamber (3) of a fuel cell (2) and/or a gas flow flowing to the anode chamber (3) of the fuel cell (2). The device is provided with a water separator (8) in an exhaust gas flow from the anode chamber (3) and with a humidifying device (11), which is designed to supply at least a part of the water to the anode chamber (3) and/or to the gas flow flowing to the anode chamber (3). The water separator (8) and the humidifying device (11) are connected by means of a line element (10). A back-flow prevention element (12), through which flow is possible in the direction of the water separator (8), is arranged between the anode chamber (3) and the water separator (8). Means for pressurizing the water separator (8) are provided, by means of which the pressure in the area of the water separator (8) can be raised above the pressure in the area of the humidifying device (11) at least at times. The water separator is pressurized by means of a gas.
