PROBLEM TO BE SOLVED: To provide a hydrogen trailer capable of improving safety while reducing workload with respect to the operation of source valves, such as easiness in simultaneously closing in emergency, etc., all source valves which are provided in each of a plurality of high-pressure hydrogen vessels mounted on the hydrogen trailer.SOLUTION: In a hydrogen trailer which is transported or detained in a state in that a plurality of high-pressure hydrogen vessels A are mounted thereon, the hydrogen trailer comprises: an emergency shutdown valve 61 provided along collective piping that leads to all of the vessels A; and source valves Aa attached to each of the vessels A, in which the source valves Aa are automatically closed in drive connection with the closing of the emergency shutdown valve 61. The emergency shutdown valve 61 and each of the source valves Aa are opened/closed by nitrogen gas supplied from a common nitrogen cylinder 71 mounted on the trailer; and each of the source valves Aa is closed by the change of pressure of the nitrogen gas during the closing the emergency shutdown valve 61. |
