PROBLEM TO BE SOLVED: To provide an air-cooling type fuel cell two-wheeled vehicle installed with a hydrogen sensor capable of early detecting a system abnormality which may occur in a fuel cell stack.SOLUTION: A fuel cell two-wheeled vehicle (10) includes: an electric motor (15) for driving a driving wheel (14); an air-cooling type fuel cell (20) for supplying electric power to the electric motor; and a hydrogen tank (21) for storing fuel gas to be supplied to the fuel cell in a vehicle body, and includes: a fan (57) for supplying air for reaction and cooling to the fuel cell and an exhaust duct (59) for exhausting the air which is supplied by the fan and cools the fuel cell to a vehicle rear side. An entrance of the exhaust duct is connected to a vehicle body rear side of the fuel cell. The fuel cell two-wheeled vehicle further includes: vehicle body inside hydrogen sensors (81, 82) for detecting hydrogen leaking from the hydrogen tank (21) and the fuel cell (20) in regions other than the exhaust duct (59) in the vehicle body and pipes and valves for connecting the hydrogen tank and the fuel cell; and a duct inside sensor (83) for detecting hydrogen in the duct.SELECTED DRAWING: Figure 4
