Abstract: A hybrid system including a high-voltage bus, a high-voltage battery electrically connected to the high-voltage bus, a fuel cell power device electrically connected to the high-voltage bus, and a drive unit electrically connected to the high-voltage bus. A controller is electrically connected to the drive unit, the fuel cell power device, and the high-voltage battery. The controller is configured to identify an application power request for the drive unit and determine a relationship between the application power request and an optimal membrane life power for the fuel cell power device. The controller is also configured to direct the fuel cell power device to operate between the optimal membrane life power and a second power. The application power request is at a power level between the optimal membrane life power and the second power.
