Abstract: 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.

Abstract: A vehicle is provided with an interior chamber apart from a passenger compartment, and a container chamber in which a high pressure gas container is accommodated. A heat generating body is accommodated in the interior chamber. Further, in the vehicle, there are formed introduction ports through which atmospheric air is introduced into the interior chamber, a communication passage that enables communication between the interior chamber and the container chamber, and a lead-out port through which the atmospheric air is led out from the container chamber. The atmospheric air that is introduced into the interior chamber through the introduction ports flows into the container chamber via the communication passage, and furthermore, is led out to the exterior of the container chamber from the lead-out port.

Abstract: A high pressure tank includes: a supplying/discharging hole; and a cap having formed therein a cap-side path which is a part of a flow path. A repelling coating interposes between a liner-side end surface facing a resin-made liner, of a flange section configuring the cap, or a flange section-facing outer surface facing the flange section, of the liner. The repelling coating is formed of a material that repels a matrix resin of a fiber-reinforced resin configuring a reinforced layer.

Abstract: A high pressure tank includes a liner that is made of resin and stores gas in a high pressure state, and a reinforcing layer that covers an outer surface of the liner. A gas flow path that guides the gas having permeated through the liner to a gas discharge path is formed in between the liner and the reinforcing layer. The gas flow path is constituted by a linear member that is arranged along the outer surface of the liner, and a sheet that is pasted on the outer surface of the liner in a manner that the sheet covers the linear member from the reinforcing layer side, whereby a space through which the gas can flow is formed around the linear member.

Abstract: A gas control system includes a high pressure tank, a temperature sensor, a pressure sensor, an injector, and a gas control ECU. The high pressure tank includes a liner, a reinforcing layer, and a discharge hole for discharging hydrogen gas from the liner. The temperature sensor detects the temperature of the reinforcing layer or the temperature around the outside of the high pressure tank. In the implementation of the gas control method, the gas control ECU, based on temperature information detected by the temperature sensor and pressure information detected by the pressure sensor, changes the timing of starting limiting control for limiting the discharge of hydrogen gas.
