  • Fuel cell propulsion system with a fuel cell stack for a motor vehicle and process for controlling a temperature of the fuel cell stack
    Patent number: 11894588
    Abstract: A computer is provided for a fuel cell propulsion system of a motor vehicle. The computer includes one or more processors receiving a temperature signal from one or more temperature sensors and a pressure signal from one or more pressure sensors. The computer further includes a non-transitory computer readable storage medium including instructions, such that the processor is programmed to determine a feedback correction based on the temperature of the coolant and the pressure drop of the coolant across the fuel cell stack. The processor is further programmed to generate a pump command signal based on the feedback correction and a nominal pump command, with the pump command signal actuating a pump to pump coolant at a target pump speed.
