Predictive freeze preparation scheduling for fuel cell propulsion system

A vehicle comprising:

• a traction battery;
• a fuel cell system;
• and
• a controller programmed to,
• responsive to a distance of the vehicle from a destination being less than a threshold distance, a state of charge of the traction battery exceeding a threshold state of charge, and the fuel cell system being on, initiate a purge of the fuel cell system via flow of air through the fuel cell system to remove moisture from the fuel cell system before arriving at the destination, and
• responsive to the distance being less than the threshold distance, the state of charge being less than the threshold state of charge, and the fuel cell system being on, preclude the purge of the fuel cell system while traveling to the destination.
