A hydrogen supply apparatus for measuring fuel consumption of a hydrogen fuel vehicle according to claim 3, wherein said measurement hydrogen tank is multiply provided, and said measurement hydrogen tanks are connected in parallel to said main pipe via each of said measurement branch pipes.5. A hydrogen supply apparatus for measuring fuel consumption of a hydrogen fuel vehicle according to claim 4, wherein said measurement branch pipe and said dummy branch pipe are releasably connected by a connector fitted with an automatic open/close mechanism that automatically opens and closes when the connector is fitted or removed, which is provided therebetween to enable separation and connection as necessary.6. A hydrogen supply apparatus for measuring fuel consumption of a hydrogen fuel vehicle according to claim 5, wherein a pressure regulator is provided in said main pipe downstream of a connection loacated furthest downstream of the connections between said measurement branch pipes and said dummy branch pipe, and said main pipe.7. A hydrogen supply apparatus for measuring fuel consumption of a hydrogen fuel vehicle according to claim 5, wherein a pressure regulator is provided for each of a plurality of said measurement branch pipes.8. A hydrogen supply apparatus for measuring fuel consumption of a hydrogen fuel vehicle according to claim 4, wherein a pressure regulator is provided in said main pipe downstream of a connection located furthest downstream of the connections between said measurement branch pipes and said dummy branch pipe, and said main pipe.9. A hydrogen supply apparatus for measuring fuel consumption of a hydrogen fuel vehicle according to claim 4, wherein a pressure regulator is provided for each of a plurality of said measurement branch pipes.10. A hydrogen supply apparatus for measuring fuel consumption of a hydrogen fuel vehicle according to claim 3, wherein said measurement branch pipe and said dummy branch pipe are releasably connected by a connector fitted with an automatic open/close mechanism that automatically opens and closes when the connector is fitted or removed, which is provided therebetween to enable separation and connection as necessary.11. A hydrogen supply apparatus for measuring fuel consumption of a hydrogen fuel vehicle according to claim 10, wherein a pressure regulator is provided in said main pipe downstream of a connection located furthest downstream of the connections between said measurement branch pipes and said dummy branch pipe, and said main pipe.12. A hydrogen supply apparatus for measuring fuel consumption of a hydrogen fuel vehicle according to claim 10, wherein a pressure regulator is provided for each of a plurality of said measurement branch pipes.13. A hydrogen supply apparatus for measuring fuel consumption of a hydrogen fuel vehicle according to claim 3, wherein a pressure regulator is provided in said main pipe downstream of a connection located furthest downstream of the connections between said measurement branch pipes and said dummy branch pipe, and said main pipe.
