In at least one embodiment, a vehicle system including a fuel cell stack and a least one controller. The fuel cell stack configured to provide energy for a vehicle. The at least one controller is programmed to control the fuel cell stack to enter into a zero gross power (ZGP) mode responsive to at least the vehicle exhibiting a negative torque demand for a period that is less than a maximum time duration. The at least one controller is further programmed to control the fuel cell stack to enter into a fuel cell shutdown mode responsive to the at least the vehicle exhibiting a negative torque demand for a period that is greater than maximum time duration.
