In a fuel cell vehicle and a method of controlling the fuel cell vehicle, when a gas pressure in a high pressure tank becomes less than a first threshold pressure, the SOC of an energy storage device is increased to a margin SOC. When the gas pressure becomes a second threshold pressure which is lower than the first threshold pressure, the amount of fuel released from the high pressure tank is limited to prevent the occurrence of buckling, and limit the travel driving force by the motor to a required limit. At the time of limiting the travel driving force, electrical energy of the energy storage device is used to provide assistance in a manner that the travel driving force by the motor becomes the travel driving force of the required limit.

A fuel cell system includes at least one fuel cell, an oxidant conveyor, a humidifier and at least one water sink. The oxidant conveyor conveys an oxidant through a supply line to the fuel cell. The humidifier introduces water into the oxidant flow. The humidifier is arranged in and/or downstream of the oxidant conveyor and upstream of the fuel cell. The water sink is arranged between the fuel cell and the oxidant conveyor. The water sink is formed and arranged in the supply line in such a way that it prevents liquid water located in the supply line from flowing to the oxidant conveyor.

A device for separating a fluid having a water and gas portion in a fuel cell system includes a fluid inlet an a fluid outlet with an outlet valve. The separating device includes a first reservoir region for collecting the water portion of the fluid. The first reservoir region includes a first outlet to feed the water portion in the direction of the fluid outlet.
