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.

A thermal management system for a fuel cell vehicle is provided. The thermal management system includes a fuel cell stack, a heater configured to use power generated by the fuel cell stack, a radiator configured to cool a coolant, a pump configured to circulate the coolant, and a valve configured to control a temperature of the coolant by adjusting a flow rate of the coolant supplied to the pump from at least one of the fuel cell stack, the heater, or the radiator.

An ECU of a fuel cell vehicle determines whether the vehicle travels on an uphill road or not. When determining that the vehicle travels on the uphill road, the ECU performs at least one of a temperature reduction control for reducing the temperature of a fuel cell stack and a humidification control for increasing the water content of the fuel cell stack, by the time the vehicle reaches the uphill road.
