摘要： PROBLEM TO BE SOLVED: To provide a hydrogen feeder enabling a reduction in the number of parts while improving a variation in the use frequency of a hydrogen tank.
SOLUTION: This hydrogen feeder 30 comprises a plurality of hydrogen tanks A1, A2, B1, B2 classified into a plurality of groups so that at least one hydrogen tank is included in each of these groups, opening/closing valves D1, D2, D3, D4 cutting off hydrogen gas released from one or a plurality of hydrogen tanks belonging to the same group, and drive circuits 41, 42 simultaneously controllably opening and closing all opening/closing valves of the hydrogen tanks belonging to the same group. Since the opening/closing valves of the hydrogen tanks belonging to the same group are controllably opened and closed by the single drive circuit, the quantity of the drive circuits can be reduced. Also, a variation in the use frequency of each hydrogen tank can be improved by changing the order of the release of hydrogen gas for each group each time when the hydrogen gas is filled in the hydrogen tanks.
