  • Hydrogen supply apparatus and hydrogen supply method for measuring fuel consumption of hydrogen fuel vehicle
    Patent number: 6978665
    Abstract: To reduce errors of measurement of fuel consumption resulting from air remaining in piping of a hydrogen supply apparatus, a hydrogen supply method for measuring fuel consumption of a hydrogen fuel vehicle comprises; a step (S02) of prior to supplying hydrogen from a measurement hydrogen tank to the hydrogen fuel vehicle, supplying hydrogen from a dummy hydrogen tank to hydrogen supply piping connecting the measurement hydrogen tank and the hydrogen fuel vehicle, to purge air in the hydrogen supply piping, and a step (S03) of after filling of the hydrogen supply piping with hydrogen from the dummy hydrogen tank, supplying hydrogen from the measurement hydrogen tank to the hydrogen fuel vehicle via the hydrogen supply piping.
