A hydrogen loading system has an orifice (120) provided as a flow restrictor between a hydrogen loading port (20) and a hydrogen tank (52) having a larger heat flow value. At the side of a hydrogen tank (50) with a small heat flow value, no orifice plate is provided. The orifice (120) has a function of increasing the channel resistance. With the foregoing, it is possible that first the hydrogen tank (50) having a smaller heat flux value is in the fully charged state, and thereafter the hydrogen tank (52) having a larger heat flux value is in the fully charged state. Alternatively, a check valve having an opening pressure ΔP 2 may be provided as a flow restrictor on the side of the larger heat flow hydrogen tank (52), and a check valve having an opening pressure ΔP 1 may be used as a flow restrictor on the side of the hydrogen tank (50) be provided with a smaller heat flux, wherein .DELTA.P 2 > .DELTA.P 1 . |
