  • Patent number: 11929527
    Abstract: A fuel cell device of a motor vehicle is disclosed. The fuel cell device includes a fuel cell, a supply air path leading to the fuel cell for a cathode supply air flow, and an exhaust air path leading away from the fuel cell for a cathode exhaust air flow. The supply air path and the exhaust air path are routed through a humidifier that humidifies the supply air and dehumidifies the exhaust air. The exhaust air path is further routed through a water separator that removes water from the exhaust air to provide evaporation water. A heat exchanger for cooling the fuel cell is provided that has an evaporative cooler for cooling the heat exchanger. The evaporative cooler is assigned to the water separator in fluidic communication and is supplied with evaporation water by the water separator.
