Abstract
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.
