Claim 17:
18. A motor vehicle, comprising a fuel cell device integrated or retrofitted in the motor vehicle, the fuel cell device including:
a fuel cell, a supply air path leading to the fuel cell for a cathode supply air flow that defines a supply air flow direction, the cathode supply air flow comprising water-containing supply air supplied to the fuel cell; and an exhaust air path leading away from the fuel cell for a cathode exhaust air flow that defines an exhaust air flow direction, the cathode exhaust air flow comprising water-containing exhaust air flowing out of the fuel cell;
the supply air path and the exhaust air path being routed through a humidifier, the humidifier communicates fluidically with a supply air and an exhaust air for humidifying the supply air and dehumidifying the exhaust air;
the exhaust air path being further routed through a water separator, the water separator communicates fluidically with the exhaust air for removing water from the exhaust air and for providing the water as evaporation water;
a heat exchanger for cooling the fuel cell that has an evaporative cooler for cooling the heat exchanger;
wherein the evaporative cooler is assigned to the water separator in fluidic communication and is supplied with evaporation water by the water separator; and
wherein the water separator is arranged upstream of the humidifier with respect to the exhaust air flow direction of the cathode exhaust air flow.
