| Zusammenfassung: | A hydrogen supply method using an inexpensive and compact hydrogen supply means to reduce a pressure of hydrogen stored in the hydrogen supply means and to supply efficiently hydrogen to a high pressure hydrogen storage means. Hydrogen is supplied under high pressure from first hydrogen supply means and from second hydrogen supply means containing a hydrogen absorbing alloy to a hydrogen storage means for storing hydrogen under high pressure. Hydrogen is supplied from the first hydrogen supply means to the hydrogen storage means until the pressure in the hydrogen storage means reaches a predetermined pressure. Thereafter, hydrogen is supplied from the second hydrogen supply means to the hydrogen storage means until the pressure in the hydrogen storage means reaches a maximum filling pressure. A plurality of the first hydrogen supply means or a plurality of the second hydrogen supply means may be used. |
