Abstract: A system and method for managing power flow in a fuel cell vehicle. The method provides a difference between a power limit signal and an actual power signal to a PI controller to generate a power offset signal. The method determines whether a fuel cell stack is able to provide enough power to satisfy a power request, and if so, adds the power request and the power offset signal to generate a stack power request signal to cause the upper power limit signal to move towards and be matched to the actual power signal. If the stack is not able to provide enough power to satisfy the load power request signal, the method subtracts the power offset signal from the power limit signal to provide a load limit signal to cause the actual stack power signal to move towards and be matched to the upper power limit signal.
