Description

The present invention relates to a railway vehicle equipped with a fuel cell.

A fuel cell is a device that uses the principle of electrolysis of water to chemically react hydrogen and oxygen to generate electricity. Since fuel cells do not emit carbon dioxide during power generation, various applications of fuel cells have been proposed to realize a decarbonized society. Also in the field of railway vehicles, fuel cell vehicles equipped with fuel cells are known. A fuel cell vehicle uses the power generated by the fuel cell as the power source for the traction motor, which is a driving power generator, and the regenerative power that the storage battery is charged by the traction motor during braking. It is one kind. For example, Patent Documents 1 and 2 disclose fuel cell vehicles.

A hybrid railway vehicle described in Patent Literature 1 includes a fuel cell, an inverter, a motor that rotates driving wheels of the vehicle, an energy storage device, and an energy control device. During acceleration, the fuel cell produces DC power, which is converted to AC power by the inverter and supplied to the motor. DC power is also supplied to an energy storage device and stored as needed. During braking, the rotational force of the wheels rotates the motor, and the electric power generated by the motor is stored in the energy storage device. The energy control device predicts the amount of energy consumption based on a known driving pattern, determines the usage ratio of the power generated by the fuel cell and the power stored in the energy storage device, and operates the inverter based on this. to control.

Japanese Patent Application Laid-Open No. 2003-134604 JP 2020-35522 A

Fuel cell vehicles require a large amount of hydrogen to travel long distances. As described in Patent Documents 1 and 2, in the case of a power vehicle equipped with both a driving power generation device and a hydrogen power generation unit in one vehicle, hydrogen storage is required due to restrictions on vehicle weight and location. Since it is difficult to add means, long-distance transportation is difficult, and the degree of freedom in organization is small. It is also conceivable to load only the hydrogen storage means on a vehicle connected to a power vehicle as in Patent Document 2, but the configuration for supplying hydrogen from the vehicle to the power vehicle becomes complicated.

The applicant of the present application is developing a railway vehicle that includes an electric locomotive that runs on the supply of electric power generated by a fuel cell and an accompanying car that is towed by the electric locomotive. In such railway vehicles, depending on the formation of accompanying cars, the traction force required for the electric locomotive may become extremely large, and a hydrogen power generation unit having a power generation capacity corresponding to this may be required. Therefore, the applicant of the present application constructed a hydrogen power generation vehicle equipped with a hydrogen power generation unit for generating power by mounting a fuel cell and a hydrogen tank independently from the electric locomotive, and connected the hydrogen power generation vehicle to the electric locomotive. Therefore, the inventors came up with the idea of enabling the hydrogen power generator to supply the electric power required by the electric locomotive.

That is, the vehicle formation according to one embodiment of the present invention is
An electric locomotive equipped with a running power generator,
at least one hydrogen-powered vehicle that is connected to the electric locomotive so that it can be connected and disconnected, and that is applied to the power source of the power generator for traveling;
It is characterized in that it is organized including the hydrogen power generation vehicle and an accompanying vehicle that is connected so as to be able to be connected and disconnected.

And the above hydrogen power generation vehicle is a hydrogen power generation vehicle applied to a power source of a power generator for running an electric locomotive,
A bogie towed by the electric locomotive;
A hydrogen storage module, and a fuel cell power generation module that receives supply of hydrogen from the hydrogen storage module and causes an electrochemical reaction between the hydrogen and oxygen in the air to generate electric power, and the hydrogen is mounted on the truck. and a power generation unit.

According to the train set and hydrogen power generation vehicle having the above configuration, the electric power generated by the hydrogen power generation unit of the hydrogen power generation vehicle is sent to the electric locomotive connected to the hydrogen power generation vehicle, and the power generator for running (that is, the main electric motor). Since the hydrogen power train is a vehicle independent from the electric locomotive, the hydrogen power train equipped with a hydrogen power generation unit having power generation capacity corresponding to the tractive force required for the electric locomotive should be connected to the electric locomotive. can be done. As a result, it is possible to arbitrarily select the number and type of accompanying vehicles to be connected to the hydrogen power generation vehicle in the vehicle formation, and to flexibly cope with various objects to be transported.

In addition, in the vehicle formation with the above configuration, when the hydrogen power generation unit runs out of fuel, the hydrogen power generation vehicle connected to the electric locomotive can be replaced with a new hydrogen power generation vehicle to continue running. In addition, the train set can accommodate long-distance transportation by providing a number of hydrogen power generation vehicles corresponding to the transportation distance.

Furthermore, in the vehicle formation of the above configuration, the heavy hydrogen power generation unit is supported by the bogie of the hydrogen power generation vehicle independent from the electric locomotive, so that the electric locomotive is equipped with the hydrogen power generation unit. Weight overweight can be avoided.

Further, in the train set of the above configuration, electric power is sent from the hydrogen generator car to the electric locomotive instead of sending hydrogen as a fuel. The configuration for sending electric power from the hydrogen generator to the electric locomotive is simpler than the configuration for sending hydrogen from the hydrogen generator to the electric locomotive.

According to the present invention, it is possible to cope with long-distance transportation and has a high degree of freedom in organization compared to a vehicle organization including a power vehicle in which both a power generation device for traveling and a hydrogen power generation unit are mounted in one vehicle. A high vehicle consist can be provided.

FIG. 4 is a diagram showing a train set 1A including hydrogen power generation vehicles 3a to 3c according to Modification 1 of the above embodiment. In the train set 1A according to the modification 1 shown in FIG. 4, three hydrogen power generation cars 3a to 3c are connected to one electric locomotive 2, and the hydrogen power generation car 3c located at the rearmost in the traveling direction An accompanying vehicle 4 is connected to the . Although the train set 1A shown in FIG. 4 includes three hydrogen power generation cars 3a to 3c, the number of hydrogen power generation cars 3 may be two or more. In addition, although several trailer vehicles 4 are shown in FIG. 4, the number of trailer vehicles 4 may be one or more.

In the train set 1A according to the modified example 1, the configurations of the electric locomotive 2 and the accompanying car 4 are substantially the same as those described in the above-described embodiment, so the configuration of the electric locomotive 2 and the accompanying car 4 is Description is omitted.

A train set 1A according to Modification 1 includes a first hydrogen power generation vehicle 3a, a second hydrogen power generation vehicle 3b, and a third hydrogen power generation vehicle 3c. The hydrogen power generators 3a to 3c are connected to each other by a mechanical connecting device 72 so that they can be connected/disconnected. This makes it easy to increase or decrease the number of hydrogen power generation cars 3a to 3c incorporated in the train set 1A.

FIG. 5 is a diagram showing the configuration of the power supply system of the train set 1A shown in FIG. As shown in FIG. 5, the first hydrogen power generation vehicle 3a is equipped with a first hydrogen power generation unit 6a. The first hydrogen power generation unit 6a, like the hydrogen power generation unit 6 described above, includes a fuel cell power generation module 61a and a hydrogen storage module 62a.

A second hydrogen power generation unit 6b is mounted on the second hydrogen power generation vehicle 3b. The second hydrogen power generation unit 6b, like the hydrogen power generation unit 6 described above, includes a fuel cell power generation module 61b and a hydrogen storage module 62b.

A third hydrogen power generation unit 6c is mounted on the third hydrogen power generation vehicle 3c. The third hydrogen power generation unit 6c, like the hydrogen power generation unit 6 described above, includes a fuel cell power generation module 61c and a hydrogen storage module 62c.

Each of the first to third hydrogen power generation units 6a to 6c is connected to a power conversion device mounted on a preceding vehicle of the vehicle on which the unit is mounted via supply wiring. More specifically, the first hydrogen power generation unit 6a is connected to the power conversion device 51 of the electric locomotive 2 by a supply wiring 71a. The supply wiring 71a connects the power conversion device 63a of the first hydrogen power generation unit 6a and the power conversion device 51 of the electric locomotive 2 in a connectable/disconnectable manner. The second hydrogen power generation unit 6b is connected to the first hydrogen power generation unit 6a by a supply wiring 71b. The supply wiring 71b connects the power conversion device 63a of the first hydrogen power generation unit 6a and the power conversion device 63b of the second hydrogen power generation unit 6b in a connectable/disconnectable manner. The third hydrogen power generation unit 6c is connected to the second hydrogen power generation unit 6b by a supply wiring 71c. The supply wiring 71c connects the power conversion device 63b of the second hydrogen power generation unit 6b and the power conversion device 63c of the third hydrogen power generation unit 6c in a connectable/disconnectable manner.

The power converters 63a to 63c of the first to third hydrogen power generation units 6a to 6c, in addition to the functions provided by the power converter 63 according to the above-described embodiment, have the power sent from other hydrogen power generation units. , and the power generated by its own power generation unit.

That is, the vehicle set 1A can cope with long-distance transportation by providing the number of hydrogen power generation vehicles 3a to 3c corresponding to the transportation distance. Also, the train set 1A can cope with a high load by providing the number of hydrogen power generation cars 3a to 3c corresponding to the required electric power. As a result, the flexibility of the formation of the vehicle formation 1A can be further increased.
