Abstract

The gas supply device disclosed in the present specification includes a cover that shuts off the periphery of the main stop valve and the connector of the gas cartridge from the outside air, and a removal device that removes impurities from the inner space of the cover in a state where the connector and the main stop valve are not connected. The controller of the gas supply device connects the main stop valve and the connector when impurities are removed from the inner space by the removal device, and opens the main stop valve. The gas supply device disclosed herein shuts off the periphery of the main stop valve and the connector from the outside air and removes impurities from the periphery of the main stop valve. Therefore, contamination of the gas supply device with impurities can be suppressed.

First claim

What is claimed is:

1 . A gas supply device that includes a connector, to which a gas cartridge in which hydrogen is stored and that is also equipped with a main stop valve that seals off the hydrogen is detachably attachable, and that supplies hydrogen to a hydrogen utilizing device via a gas channel that is connected to the connector, the gas supply device comprising:
a cover for isolating a vicinity of the main stop valve of the gas cartridge that is attached and the connector from ambient atmosphere; a removal device for removing an impurity from an inner space of the cover in a state in which the connector and the main stop valve are not in contact; and a controller for connecting the main stop valve and the connector following the impurity being removed from the inner space by the removal device, and opening the main stop valve.

2 . The gas supply device according to claim 1 , further comprising:
an actuator for bringing one of the gas cartridge and the connector closer to the other, wherein when the actuator brings the gas cartridge closer to the connector up to a first position, the cover comes into tight contact with the gas cartridge, and when the gas cartridge is brought closer to the connector up to a second position that is closer to the connector than the first position, a push rod of the connector abuts the main stop valve and opens the main stop valve.

3 . The gas supply device according to claim 1 , wherein the cover isolates an entirety of the gas cartridge from the ambient atmosphere.

4 . The gas supply device according to claim 2 , further comprising:
an inert gas supplier for supplying an inert gas to the inner space.

5 . The gas supply device according to claim 3 , further comprising:
an inert gas supplier for supplying an inert gas to the inner space.
