される。SUMMARY OF THE INVENTION It is an object of the present invention to provide an economical method for filling hydrogen into a high-pressure container, by which high-pressure hydrogen can be obtained at low cost by adopting an extremely simple means. To achieve the above object, according to the present invention, a hydrogen generating substance which reacts with water to generate hydrogen and water are weighed in a high pressure vessel so as to obtain a target high hydrogen pressure, and then the hydrogen is removed. The generated substance and the water are put into the high-pressure container through its supply port, and thereafter,
A method for filling hydrogen into a high-pressure container is provided, in which the supply port is closed and the hydrogen generation substance and the water react to cause the hydrogen pressure in the high-pressure container to reach the target high hydrogen pressure.

るまで，容器内圧力は一定に保たれることになる。The hydrogen pressure reached by the reaction between the hydrogen generating substance and water is determined by the amount of hydrogen generated at the temperature reached by the reaction and is determined equilibrium. The hydrogen generation amount of the hydrogen generating substance which is extremely active against water at around room temperature generally does not largely depend on the pressure inside the container, and therefore reaches the hydrogen pressure stoichiometrically determined. However, when the pressure in the container during the reaction is sufficiently high and the reaction does not proceed equilibrium, the hydrogen pressure does not reach the stoichiometric pressure and becomes constant at the equilibrium pressure. Unreacted hydrogen generating material will remain. That is, the pressure in the container is kept constant until all unreacted hydrogen generating substances have reacted.

によれば，これらの問題点はことごとく解消される。As a method of filling hydrogen into the vehicle-mounted high-pressure container 1, in order to shorten the filling time, hydrogen is filled in the buffer tank by the high-pressure compressor at the hydrogen station, and the high-pressure hydrogen in the buffer tank is charged into the vehicle under high pressure. A means of transferring to a container is also considered, but in this case, the hydrogen pressure in the buffer tank must be higher than that in the high-pressure container 1, so that a large amount of hydrogen is needed to fill the buffer tank with hydrogen. Need a lot of energy. Further, when a cascade type filling system in which a plurality of buffer tanks are combined is used, the system becomes large and the space occupied by the system is increased. According to the present invention, all of these problems are solved.
