Abstract
Fuel cell coolant loop (2) is to be controlled to maintain set point 38 temperature of the return coolant. Waste heat heat exchanger 10 is controlled to maintain set point 22 temperature in the waste heat fluid. Heat rejection heat exchanger removes additional heat as required to maintain the set point (38) temperature. If both set point temperatures cannot be maintained, a control override allows the waste heat fluid temperature to drop.
