1. A modular system of a vehicle comprising:
a shaft; and
a plurality of parallel systems that are electrically isolated from one another, the plurality of parallel systems comprising:
a first parallel system for rotating the shaft, the first parallel system comprising a first motor coupled to the shaft to rotate the shaft, a first parallel system power generation module coupled to the first motor to drive the first motor, a fuel cell electrically connected to supply electrical power to the first motor, and a battery electrically connected to supply power to the first motor; and
a second parallel system to rotate the shaft, the second parallel system comprising a second motor coupled to the shaft for rotating the shaft, and a second parallel system power generation module coupled to the second motor to drive the second motor.
