Abstract

PURPOSE:To eliminate the possibility of combustion and explosion of hydrogen gas and to discharge said hydrogen gas safely by substituting an inert gas for air within piping before discharging said hydrogen gas. CONSTITUTION:When hydrogen gas within a generator 1 is discharged into the air, an inert gas is sealed from an inert gas feeder 5 provided between a hydrogen gas discharge valve 3 and an atmospheric escape pipe 4 into a piping 4 leading from the hydrogen gas discharge valve 3 to the air. Then, after air is not present within the piping 4, the hydrogen gas discharge valve 3 is opened and the hydrogen gas within the generator 1 is discharged into the air. Not only a timer but also a flow meter 21 and a gas concentration meter 22 may be used in order to know the time for opening the hydrogen gas discharge valve 3. Also, nitrogen gas, carbon dioxide gas, argon gas and the like can be cited as said inert gas.

Hydrogen gas is supplied to the generator 1 from a hydrogen gas supply device 2 . When releasing the hydrogen gas in the generator 1 into the atmosphere, open the hydrogen gas atmosphere release valve 3 and open the atmosphere release pipe 4.
The conventional method was to release hydrogen gas into the atmosphere through a In the present invention, since the inert gas supply device 5 is provided between the hydrogen gas release valve 3 and the atmosphere release pipe 4, first, the inert gas is supplied from the hydrogen gas release valve 3 by the inert gas supply device 5. The hydrogen gas is sealed in a pipe leading to the atmosphere, and after the atmosphere is no longer present in the pipe, the hydrogen gas release valve 3 is opened and the hydrogen gas in the generator 1 is released into the atmosphere.
