2.0.1 Hydrogen fueling station
A dedicated place for fueling hydrogen into fuel cell vehicles.
2.0.2 Automobile gasoline and hydrogen fueling station
A dedicated place with oil storage facilities that can not only fuel gasoline and diesel for the
vehicles, but also can fuel vehicle-used compressed hydrogen or mixture of hydrogen and
natural gas for the fuel cell vehicles, or hydrogen-storing cylinder for the hydrogen internal
combustion engine vehicle or hydrogen and natural gas hybrid vehicle.
2.0.3 Automobile hydrogen and gas fueling station
A dedicated place with gas storage facilities that can not only fuel gas for vehicles, but also fuel
vehicle-used compressed hydrogen or mixture hydrogen and natural gas for the fuel cell
vehicles, or hydrogen internal combustion engine vehicles, or hydrogen and natural gas hybrid
vehicle.
2.0.4 Fuel cell vehicle
A vehicle that uses hydrogen as fuel and a fuel cell engine as a power source to transport goods
or people.
2.0.5 Hydrogen dispenser
A special equipment for fueling hydrogen storage bottles of fuel cell vehicles with hydrogen
and equipped with control, metering and pricing devices.
2.0.6 Hydrogen filling hose
A metal hose that connects the hydrogen dispenser and the hydrogen filling nozzle.
2.0.7 Hydrogen filling nozzle
A filling device with a hydrogen on-off function that is inserted into the receptacle of a fuel cell
vehicle.
2.0.8 Receptacle
A connector that connects the hydrogen filling nozzle and the vehicle-mounted hydrogen
storage system.
2.0.9 Vessels for hydrogen gas storage
A hydrogen storage device that is fixedly installed in a hydrogen fueling station and is used to
5 General Layout
5.0.1 The equipment arranged in the station shall have reliable infrastructure, and the buildings
and structures in the station shall meet the relevant requirements for seismic design in the
current national standards GB 50011 Code for Seismic Design of Buildings, and GB 50191
Design Code for Anti-Seismic of Special Structures.
5.0.2 The fence setting of the hydrogen fueling station shall comply with the following
provisions:
1 When the distance between the process facilities of the hydrogen fueling station and the
buildings and structures outside the station is less than or equal to 25m, and less than or
equal to 1.5 times the safe distance in Table 4.0.4, the adjacent side shall be set non-
combustible solid wall at a height of no less than 2.2m.
2 A non-physical fence should be set up on the side facing the entrance and exit roads.
5.0.3 The vehicle entrance and exit of the hydrogen fueling station shall be set up separately.
5.0.4 Roads within the station area shall comply with the following provisions:
1 The width of a single lane shall be no less than 3.5m, and the width of a double lane shall
be no less than 6m.
2 The turning radius of the road within the station is determined according to the model of
the hydrogen fueling vehicle; and should be no less than 9 m. The road slope shall be no
greater than 6%, and should be sloping toward the outside of the station. The unloading
parking space of the hydrogen transport device should be designed with a flat slope.
3 The loading and unloading parking spaces and road surfaces within the station shall use
non-fire floors.
5.0.5 A canopy should be set on the installation site of the hydrogen filling island and hydrogen
dispenser; the canopy should be made of non-combustible materials. The lower part of the
canopy should be flat and made into a structure that does not accumulate hydrogen.
5.0.6 The design of the hydrogen filling island shall comply with the following provisions:
1 The hydrogen filling island shall be 0.15m~0.2m higher than the floor of the hydrogen-
filling parking space.
2 The width of the hydrogen filling island should be no less than 1.2m.
5.0.7 The layout of the hydrogen transport unit in the hydrogen fueling station shall comply
with the following provisions:
6 Hydrogen Fueling Technics and Main Equipment
6.1 Quality, pressure regulation and metering of hydrogen
6.1.1 The quality of the hydrogen gas entering the hydrogen fueling station shall comply with
the high-purity hydrogen quality standards specified in the current national standard GB/T
3634.2 Hydrogen - Part 2: Pure Hydrogen, High-Purity Hydrogen and Ultra-Pure Hydrogen.
6.1.2 External hydrogen supply should be provided by hydrogen transport unit or pipeline to
supply hydrogen. When using pipelines to supply hydrogen, a pressure regulating device and a
flow metering device should be installed on the incoming pipeline.
6.1.3 For the equipment and pipelines in the hydrogen fueling station, wherever pressure needs
to be displayed, pressure detection points shall be set up, and a safety pressure relief device for
high-pressure gas pressure relief should be installed, when the pressure gauge is disassembled.
The measuring range of the pressure gauge shall be 2 times the working pressure, and the
accuracy of the pressure gauge shall be no lower than level 1.5.
6.2 Hydrogen storage system and equipment
6.2.1 The working pressure of the hydrogen storage system in the hydrogen fueling station shall
be determined based on the hydrogen charging pressure of the hydrogen fueling vehicle. When
the hydrogen charging pressure is 35MPa ~ 70 MPa, the working pressure of the hydrogen
storage system of the hydrogen fueling station is generally 40 MPa ~ 100 MPa. The hydrogen
storage dev...
