Title:

GAS FILLING DEVICE AND GAS FILLING METHOD

Document Type and Number:

WIPO Patent Application WO/2014/119398

Kind Code:

A1

Abstract:

In order to implement the filling of gas without requiring a booster pump, and to reduce the device size and the filling time, this gas filling device (11), which fills a filling container (12) with a vaporized gas to achieve a prescribed pressure, is equipped with: a temporary storage heat-insulating container (14), which has a heat-insulating function and stores an amount of liquefied gas representing the amount when the filling container (12) is filled to the prescribed pressure of vaporized gas at normal temperature; and a connecting passage (15), which is for connecting a fluid outlet (14a) of the temporary storage heat-insulating container (14) and a fluid inlet (12a) of the filling container (12) and introducing hydrogen gas from the temporary storage heat-insulating container (14) to the filling container (12). The connecting passage (15) is equipped with: opening/closing means (15a, 15b) for opening/closing the fluid outlet (14a) and the fluid inlet (12a); an introducing/vaporizing unit (15f) equipped with a buffer means (21) that alleviates the momentum of the passing gas flow and a warming unit (22) having a temperature at which the liquefied hydrogen is vaporized; and an attachment/detachment unit (15c) coupled to the filling container (12) in a detachable manner.
