Zusammenfassung:	A heating system for optimizing execution of heating tasks in a fuel cell vehicle is disclosed, the system including a stack coolant loop with a fuel cell stack, a primary pump, and a radiator module. A bypass coolant loop is disposed parallel with and is connected to the stack coolant loop between the fuel cell stack and the radiator module. The bypass loop including a cabin heat exchanger and a coolant heater, along with a secondary pump for pumping coolant through the heaters when desired.
