GAS CHARGING METHOD AND EQUIPMENT THEREFOR

Document Type and Number:

Japanese Patent JP2005273871

Kind Code:

A

Abstract:

To provide the gas charging method and the equipment which enable a fill-up with the gas of aimed pressure in a short time by controlling the heat generation and without over charging when charging the gas.

Connecting the water pressure inlet/outlet system and the hydrogen gas filling system with the hydrogen gas tank 2 installed on a fuel-cell car and filling up the pressurized water W in advance before gas charging into the hydrogen gas tank 2, and it presses previously so that the internal pressure becomes the preload P2. Filling up the hydrogen gas G which keeps the preload condition and boosts its pressure to the aimed pressure P3 into the hydrogen gas tank 2, the water W is discharged from the hydrogen gas tank 2 by the pressure of hydrogen gas G.
