  • Method for spraying a fluid onto a charge air cooler of a motor vehicle
    Patent number: 10358972
    Abstract: A method for spraying a fluid onto a charge air cooler of a motor vehicle includes measuring a first temperature with the aid of a first sensor of the motor vehicle; measuring a second temperature with the aid of a second sensor of the motor vehicle; comparing the first temperature with a first reference temperature by a controller of the motor vehicle; comparing the second temperature with a second reference temperature by the controller of the motor vehicle if the first temperature is higher than the first reference temperature or equal to the first reference temperature; and spraying at least some of the fluid onto the charge air cooler during a spray-on cycle if the second temperature is higher than the second reference temperature or equal to the second reference temperature.

  • Fuel cell system
    Patent number: 8808938
    Abstract: A fuel cell system includes at least one cooling channel that extends between a housing and a fuel cell stack disposed within the housing. The cooling channel has an inlet and an outlet for producing a gas flow in the cooling channel. As a result, a gas flow may be used for cooling and at the same time may be used for ventilation of the cathode.
