A humidifier for a hydrogen recirculation system of a fuel cell vehicle is provided not to need an additional power source, and to prevent the contamination of parts caused by noise and water discharge. A humidifier(10) for a hydrogen recirculation system of a fuel cell vehicle heats air supplied through an air blower(120) to remove moisture. The humidifier is bypassed in a hydrogen gas recirculation device(110) recirculating hydrogen gas discharged from a stack(100) and is connected to the hydrogen gas recirculation device as a medium through a hydrogen gas return passage(11). A hydrogen purging valve(13) controls to prevent the leakage of hydrogen gas flowed in a hydrogen purging pipe and to discharge hydrogen and water. |
