Combination fuel cell stack and electrochemical battery system provides stable and redundant electrical power to one or more traction motors. The electrochemical battery packs comprise modules that are switched between a low-voltage parallel configuration connecting to the fuel cell stack and a high-voltage series configuration connecting to the traction motors, thereby harvesting low-voltage energy from the fuel cells and deploying that energy as high-voltage power to the motor. The plurality of electrochemical battery packs can be switched such that at least one is always connected to the traction motor for continuity of power.
