A power distribution control system for a hybrid fuel cell vehicle is provided. The system includes a high energy converter (HEC) for providing current from an electrical bus to the battery, or from the battery to the bus. As a vehicle load changes, the HEC adjusts the battery current flow. A current command is sent to a fuel cell controller so that the fuel cell current output is adjusted. As the fuel cell current output changes, the HEC further adjusts the battery current flow, until there is a zero net current flow to and from the battery. At this point, a state of equilibrium is reached and the fuel cell provides all the current required by the vehicle loads.
