The method comprises obtaining a value of power output of the fuel cell system, the value indicating a power demand from the fuel cell system during operation of the vehicle; and adjusting a value of a target coolant inlet temperature of a coolant at a coolant inlet of the fuel cell stack to vary between a first target temperature level and a second target temperature level, in dependence on the value of the power output, to optimize a duration of time during which the target temperature is different from the first target temperature level and to optimize a value of one or more parameters related to operation of the fuel cell system.

A retarder (250) is configured to be coupled to a pair of wheels (204) of the vehicle. The second water recirculation loop may be selectively used for cooling the propulsion device and for providing water to the retarder for water braking. There is also provided a method (100, 110) for cooling a propulsion device of a vehicle and water braking a pair of wheels of a vehicle.
