A freight vehicle has a loading space, on which freight is loaded, rearward of a vehicle cabin in which an occupant rides. The freight vehicle includes a fuel cell mounted below the vehicle cabin and functioning as an electric power source, a storage portion disposed between the vehicle cabin and the loading space, and a tank disposed in the storage portion and stores fuel gas that is supplied to the fuel cell, and a radiator installed in the storage portion and performs heat exchange between air and a coolant that is supplied to the fuel cell.

Freight vehicle

A combination vehicle includes a tractor and a trailer towed by the tractor. The trailer includes a first tank that is configured to store a high-pressure gas as a fuel used by the tractor to travel. The tractor includes a second tank that is configured to store a high-pressure gas as a fuel used by the tractor to travel. The combination vehicle is configured to travel using the fuel supplied from the first tank and the second tank.

Combination vehicle, trailer, and tractor

A transport vehicle configured to run on electricity generated by a fuel cell includes: a body having a cargo space for freight; a chassis frame located below the body and supporting the body; and a tank unit including a plurality of tanks that stores fuel gas to be used for power generation by the fuel cell and a connecting portion connecting the tanks, the tank unit being located between the cargo space and the chassis frame.

Transport vehicle

A fuel cell system includes at least one pressure reducing valve connected to a downstream side of a hydrogen gas tank, a hydrogen gas flow path including a first flow path connected to a downstream side of the pressure reducing valve and a plurality of second flow paths connected to a downstream side of the first flow path and branched from the first flow path, a plurality of injector units, each of which is connected to each of the second flow paths, a plurality of fuel cell stacks, each of which is connected to each of the injector units, and a control unit controlling opening and closing of the injector units. The control unit sets valve closing periods of the injector units to periods deviating from each other such that at least one of the injector units is always opened when the fuel cell system satisfies a predetermined operating condition.

Fuel cell system

A gas supply system includes: a gas tank; an unbalanced pressure reducing valve that reduces a pressure of the gas supplied from the gas tank; a pressure sensor that detects an outlet-side pressure of the pressure reducing valve; a flow rate changing unit that changes an outlet-side flow rate of the pressure reducing valve; and a control unit. The control unit changes the outlet-side flow rate between first and second flow rates, obtains a first pressure, which is a detection value of the pressure sensor when the outlet-side flow rate is the first flow rate, and a second pressure, which is a detection value of the pressure sensor when the outlet-side flow rate is the second flow rate, and estimates an inlet-side pressure of the pressure reducing valve using the relationship among the first flow rate, the second flow rate, and the difference between the first and second pressures.

Gas supply system and method for estimating infernal pressure of gas tank

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.
