Abstract: An electrolyte station is used for electrolyte replacement in a redox flow battery that is mounted to a vehicle. The electrolyte station includes: a stand that includes a connector that connects to a connection socket that connects to an electrolyte tank in the redox flow battery; a recovery tank that stores a recovered electrolyte; a filling tank that stores a charged electrolyte; a recovery line that connects the connector in the stand and the recovery tank; and a filling line that connects the connector in the stand and the filling tank. In response to the connector being connected to the connection socket, the electrolyte station enables the used electrolyte removed from an electrolyte tank to be recovered to the recovery tank through the recovery line, and enables the charged electrolyte stored in the filling tank to be supplied the electrolyte tank through the filling line.

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 fuel cell system includes a supply channel having first channels respectively connected with tanks, and a second channel merged with each of the first channels; first on-off valves of the first channels; a second on-off valve of the second channel; and a controller configured to control opening and closing of the first on-off valves and the second on-off valve. In a state where the second on-off valve is closed, the controller supplies first electric power used for opening the first on-off valve against a first differential pressure to at least one first on-off valve, and supplies second electric power, smaller than the first electric power and used for opening the first on-off valves against a second differential pressure smaller than the first differential pressure, to the first on-off valves other than the at least one first on-off valve.
