1. A hybrid propulsion system for a vehicle, the hybrid propulsion system comprising:
an internal combustion engine (ICE) having a first output that drives a generator, the generator providing a first output voltage;
a fuel cell having a second output providing a second output voltage;
a hydrogen storage tank configured to store hydrogen and selectively and alternatively supply the hydrogen to both of the ICE and the fuel cell;
a battery pack that selectively and alternatively receives the first and second output voltage to charge the battery pack;
an electric drive motor that receives power from the battery pack to drive a drive wheel of the vehicle to propel the vehicle; and
a controller that receives vehicle inputs and determines operational set points of the ICE and the fuel cell representative of an amount of the first and second output voltages to direct to the battery pack based on operating conditions.
