A hydrogen supply method is provided which, by use of an inexpensive and compact hydrogen supply means, can reduce the pressure of the hydrogen stored in said hydrogen supply means, and moreover can efficiently supply hydrogen to a high pressure hydrogen storage means. Hydrogen is supplied from first hydrogen supply means 1, 2, 3 for supplying hydrogen stored under high pressure and second hydrogen supply means 4, 5, 6 for supplying hydrogen stored in a hydrogen absorbing alloy to a hydrogen storage means 9 for storing hydrogen under high pressure. Hydrogen is supplied from the first hydrogen supply means 1, 2, 3 to the hydrogen storage means 9 until the hydrogen pressure in the hydrogen storage means 9 reaches a predetermined pressure. After this step, hydrogen is supplied from the second hydrogen supply means 4, 5, 6 to the hydrogen storage means 9 until the hydrogen pressure in the hydrogen storage means 9 reaches a maximum filling pressure. A plurality of the first hydrogen supply means 1 or a plurality of the second hydrogen supply means 4 are used.
