3 Terms and Definitions
For the purposes of this Standard, the following terms and definitions and those
defined in GB/T 24499 and GB/T 50516 apply.
3.1
hydrogen refueling station
A stationary special site which is used to fill hydrogen fuel for vehicle gas storage
cylinders of hydrogen energy vehicles, including hydrogen cell vehicles or hydrogen
internal combustion engine vehicles or hydrogen mixed fuel vehicles and so on.
3.2
combined hydrogen refueling station
4.7 When the hydrogen refueling stations are combined with charging stations, the
design of charging process facilities shall be as specified in GB 50966 and GB/T 29781.
5 Site Selection
5.1 The hydrogen refueling stations and all kinds of combined stations shall conform
to the town planning, which shall be located in places with convenient transportation;
they shall not be located in places where there is much dust or corrosive gases or
places which are low lying and possibly accumulate water.
5.2 A buffer distance or buffer area may preferably be provided between the
hydrogen refueling stations combined with charging stations and municipal roads
outside the stations for the convenience of access and waiting of electric vehicles.
5.3 The fire-protection distance between the process facilities of the hydrogen
stations, hydrogen-gas combined refueling stations and hydrogen-oil combined
refueling stations, and the buildings and structures outside the stations, shall be as
specified in GB 51516.
5.4 The fire-protection distance between the hydrogen process facilities of the
combined hydrogen stations combined with charging stations, and the buildings and
structures outside the stations, shall be as specified in GB 51516.
5.5 The fire-protection distance between the charging process facilities of the
combined hydrogen stations combined with charging stations, and the buildings and
structures outside the stations, shall be as specified in GB 50016 and GB 50966.
6 Layout
6.1 The fire-protection distance between the facilities within the hydrogen refueling
stations, hydrogen-gas combined refueling stations and hydrogen-oil combined
refueling stations shall be as specified in GB 50516 and GB 50156.
6.2 The installation locations of the charging process facilities of the combined
hydrogen refueling stations combined with charging stations shall be more than 3 m
from the boundary lines of the explosion hazard areas; and the classification of
explosion hazard areas shall be as specified in GB 50516.
6.3 Cross arrangement of the process facilities of different media for hydrogen
refueling, gas refueling, oil refueling, charging etc. within the hydrogen refueling
stations and all kinds of combined hydrogen refueling stations is not advisable.
9.1.3 The direct current supply circuits of the water electrolysis hydrogen production
equipment shall be made of copper conductors, which shall be laid in low places or
trenches; and when bare bus bars must be used, measures shall be taken to prevent
spark discharge.
9.1.4 Before starting the water electrolysis hydrogen production equipment, check all
protective and safety facilities to ensure they are in sound conditions, such as pressure
regulating devices, blow-down purging and analytical facilities, safety valves and all
kinds of indication and regulating instruments. Before starting the systems, check and
ensure the oxygen content in nitrogen entrained into the systems by purging
replacement is less than 0.5%.
