Modular fuel cell system architecture and a control system for distributing power to the modules

A modular system of a vehicle comprising:

• a shaft;
• a first parallel system comprising a first motor coupled to the shaft to rotate the shaft, and a fuel cell electrically connected to supply electrical power to the first motor;
• and
• a second parallel system electrically isolated from the first parallel system, the second parallel system comprising a second motor coupled to the shaft to rotate the shaft, and a second fuel cell electrically connected to supply electrical power to the second motor.
