To provide a moving body provided with a plurality of high-pressure tanks and a plurality of temperature sensors and capable of, without unnecessary increasing the number of them, determining a failure of the temperature sensor.
A fuel cell vehicle 2 determines that there is a failure in one of a plurality of temperature sensors when a differential value ΔT obtained by subtracting the minimum value from the maximum value of detection values of the plurality of temperature sensors is larger than a failure determination threshold σ0 determined with reference to errors of the plurality of temperature sensors after the passage of a predetermined time from the filling start point of time at which the start of the filling of hydrogen gas is determined, and determines that there is a failure in one of the plurality of temperature sensors when the differential value ΔT is larger than the failure determination threshold σ0+Δt1 until the passage of the predetermined time from the filling start point of time.
