Abstract

A hydrogen supply system comprises a hydrogen station placed near a railroad track and configured to supply hydrogen to a moving body that is driven with a fuel cell used as an electric power source; and a train provided with a hydrogen tank and configured to run along the railroad track and transport hydrogen to the hydrogen station.

First claim

What is claimed is:

1. A hydrogen supply system, comprising:
a hydrogen station placed near a railroad track and configured to supply hydrogen to a moving body that is driven with a fuel cell used as an electric power source; and
a train provided with a hydrogen tank and configured to run along the railroad track and transport hydrogen to the hydrogen station.

2. The hydrogen supply system according to claim 1 ,
wherein the train is provided with a dispenser that is configured to supply hydrogen to the moving body at the hydrogen station.

3. The hydrogen supply system according to claim 1 ,
wherein the moving body is a routine-run vehicle running along a scheduled route and is scheduled to reach the hydrogen station according to a scheduled stop time of the train at the hydrogen station.

4. The hydrogen supply system according to claim 1 ,
wherein the train is provided with a fuel cell that is used as an electric power source to run the train along the railroad track.

5. A train, comprising:
a hydrogen tank on a train car running on railroad track; and
a dispenser configured to supply hydrogen from the hydrogen tank to a moving body that is driven with a fuel cell used as an electric power source.

6. The train according to claim 5 , further comprising:
a fuel cell; and
a motor for railroad track running that is driven with electric power generated by the fuel cell.

7. A hydrogen supply method, comprising:
causing a train that runs along a railroad track and that is provided with a hydrogen tank to transport hydrogen to a hydrogen station placed near the railroad track; and
supplying hydrogen to a moving body that is driven with a fuel cell used as an electric power source, at the hydrogen station.
