Fuel cell electric vehicles –
Onboard hydrogen system - Test methods
1 Scope
This Standard specifies the test methods for onboard hydrogen system of fuel
cell electric vehicles.
This Standard is applicable to fuel cell electric vehicles which use compressed
hydrogen as fuel, of which the working pressure does not exceed 35 MPa when
it works at 15°C of ambient temperature.
2 Normative references
The following referenced documents are indispensable for the application of
this document. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any
amendments) applies..

3 Terms and definitions
The terms and definitions defined in GB/T 24548 apply to this document.
4 Test conditions
4.1 Vehicle conditions
4.1.1 Onboard hydrogen system shall be manufactured according to product
design and other technical documents approved by prescribed procedures. The
certificate shall be provided.
6.1.1.3 When hydrogen storage container is mounted and fastened,
respectively apply a force 8 times hydrogen storage vessel gravity full of
nominal operating pressure hydrogen at X, Y and Z directions. Measure and
check the relative displacement between hydrogen storage container and
holder.
6.1.1.4 Check if the metal parts of supporting and securing pipeline are in
contact with the piping, except the welding BETWEEN the piping AND
supporter and fastener.
6.1.1.5 Check the neat arrangement of rigid pipeline. Check if the rigid
pipeline is in contact with or rub with the adjacent parts. Check if the pipeline
has seismic resistance and measures to eliminate the influence of thermal
expansion and contraction. For bending pipes, measure its radius of the axis of
curvature. Measure the interval distance between supporting points of piping.
6.1.1.6 Measure the distance between the installation location of the
attachment of hydrogen storage vessel and vehicle edge.
6.1.1.7 Check the effect of hydrogen storage vessel, piping on its possible
heat source. Check if there is appropriate insulation protection measures. For
the hydrogen storage vessel and piping directly exposed to the sun, check if
there is necessary coverings.
6.1.2 Hydrogen leakage
6.1.2.1 Hydrogen leakage: fill the hydrogen storage vessel in the test vehicle
to 100% of working pressure, and put it in a hermetic space for 8 h according
to provisions. Measure the hydrogen permeation rate.
6.1.2.2 Check if hydrogen detector is installed inside the enclosed or semi-
enclosed spaces of the hydrogen system. Use standard gas mixture to check if
the detector be able to perform the real-time detection on concentration of
hydrogen leak and send the signal to the hydrogen leak warning device. Check
if the hydrogen leak warning device be able to send different warning signals
according to the concentration of hydrogen leak.
6.1.2.3 Check if the hydrogen leak warning device is installed at the place
where driver can easily recognize.
6.1.2.4 Check if the hydrogen detector can send out failure warning signal to
the driver when short circuit, open circuit failure happen to the detector.
6.1.3 Refuelling receptacle
6.1.3.1 Check if refuelling receptacle shape and size comply with the
requirements of GB/T 26779-2011. Measure the installation place and height of
