Abstract

Provided is a gas supply system for supplying hydrogen to a vehicle, the vehicle including: a tank loaded with a hydrogen storage alloy, storing and releasing hydrogen; and a thermal medium distribution unit attached to the tank and configured such that a thermal medium for heating or cooling the hydrogen storage alloy is distributable from outside, includes: a reservoir reserving hydrogen at a pressure of 0.2 MPa or greater and less than 3.0 MPa; a hydrogen flow path connectable to the vehicle for supplying hydrogen from the reservoir to the tank; a cooling medium reservoir reserving the thermal medium for cooling; and a thermal medium flow path connectable to the vehicle for distributing the thermal medium to the thermal medium distribution unit in the vehicle, in which the hydrogen flow path and the thermal medium flow path are combined at least at an end portion connectable to the vehicle.

First claim

The invention claimed is:

1. A gas supply system for use in supplying hydrogen to a vehicle, the vehicle comprising: a tank that is loaded with a hydrogen storage alloy, stores and releases hydrogen; and a thermal medium distribution unit that is attached to the tank and is configured such that a thermal medium for heating for the purpose of heating the hydrogen storage alloy or a thermal medium for cooling for the purpose of cooling the hydrogen storage alloy is distributable from an external space, the gas supply system comprising:
a reservoir that reserves hydrogen at a pressure of greater than or equal to 0.2 MPa and less than 3.0 MPa;
a hydrogen flow path that is connectable to the vehicle for supplying hydrogen from the reservoir to the tank in the vehicle at a pressure of greater than or equal to 0.2 MPa and less than 3.0 MPa;
a cooling medium reservoir that reserves the thermal medium for cooling in a cooled state;
a thermal medium flow path that is connectable to the vehicle for selectively distributing the thermal medium for heating or the thermal medium for cooling to the thermal medium distribution unit in the vehicle;
a pump that delivers the thermal medium for heating to the thermal medium distribution unit in the vehicle;
an other pump that delivers the thermal medium for cooling to the thermal medium distribution unit in the vehicle; and
a switching valve that allows the thermal medium flow path to selectively connect between the thermal medium for cooling and the thermal medium for heating, wherein
the hydrogen flow path and the thermal medium flow path are combined at least at an end portion connectable to the vehicle.

2. The gas supply system according to claim 1 , further comprising
a coupler that is connectable to the vehicle in a detachable manner, wherein
the hydrogen flow path and the thermal medium flow path are combined in the coupler.

3. The gas supply system according to claim 1 , wherein
the thermal medium for cooling at a temperature of greater than or equal to −40° C. and less than or equal to 0° C. is distributed in the thermal medium distribution unit in the vehicle.

4. The gas supply system according to claim 1 , wherein
the pump is an air pump.

5. The gas supply system according to claim 4 , further comprising
a coupler that is connectable to the vehicle in a detachable manner, wherein
the hydrogen flow path and the thermal medium flow path are combined in the coupler.

6. The gas supply system according to claim 4 , wherein
the thermal medium for cooling at a temperature of greater than or equal to −40° C. and less than or equal to 0° C. is distributed in the thermal medium distribution unit in the vehicle.
