  • Vehicle comprising an electricity supply system
    Patent number: 11465515
    Abstract: The invention concerns a vehicle comprising an electricity production unit configured for generating an electrical current, a transformer unit and a fuel storage unit, the production unit comprising at least two fuel cell stacks and a single first electrical connection interface for transmitting the electrical current to the transformer unit. The production unit further comprises a single cooling circuit, an air supply circuit and a single gaseous hydrogen supply circuit for supplying gaseous hydrogen, from the fuel storage unit, to each fuel cell stack. The production unit is separate from the fuel storage unit and connected to the fuel storage unit by a single connection interface, the production unit being removable from the vehicle as an integrated unit independently from the fuel storage unit.
