Safety requirement of fuel cell stack
1 Scope
This Standard specifies the safety requirements for fuel cell stack for fuel cell
electric vehicles in terms of hydrogen safety, electrical safety, and mechanical
structure, etc.
This Standard applies to the proton exchange membrane fuel cell stack for
vehicles. This Standard only deals with hazards to the outside of the human
body and fuel cell stacks, and does not involve protection of the interior of the
fuel cell stack, assuming that such internal damage does not pose a hazard to
the outside of the fuel cell.

3 Terms and definitions
What defined in GB/T 24548 and GB/T 28816 and the following terms and
definitions are applicable to this document.
3.1 Fuel cell stack for vehicle
5.2 Safety requirement of airtightness
USE pressure drop method to test the airtightness of fuel cell stack. The result
shall not be lower than 85% of the initial pressure.
5.3 Electrical safety requirements
5.3.1 Requirement of insulation property
When the fuel cell stack is filled with coolant and the coolant is in a cold cycle
state, the ground insulation of positive and negative electrodes shall not be
lower than 100 Ω/V.
5.3.2 Requirement for protection of persons against electric shock
The requirement for protection of persons against electric shock of fuel cell
stack shall comply with the relevant provisions of GB/T 18384.3.
5.3.3 Requirement of ground protection
When the output voltage of fuel cell stack is higher than 60 V, the fuel cell stack
needs to have a grounding point. The resistance between the grounding point
and all bare metals shall be less than 0.1 Ω.
6 Test methods
6.1 Mechanical shock
After the fuel cell stack is installed and fixed, in 3 axial directions. X direction, Y
direction, and Z direction, PERFORM shock test with a shock acceleration of
5.0 g. The mechanical shock pulse is a half sinusoidal waveform and lasts for
15 ms, once in each direction.
Note. The X direction is the vehicle’s heading direction. The Y direction is the lateral
direction. The Z direction is the vertical direction.
6.2 Airtightness
The fuel cell stack is in a cold state. CLOSE the hydrogen exhaust port, air
exhaust port, and coolant outlet of the fuel cell stack; and at the same time,
ADD helium-nitrogen mixed gas to the hydrogen flow channel, air flow channel,
and coolant flow channel. The helium concentration shall not be less than 10%.
The pressure shall be set at the normal working pressure (gauge pressure).
After the pressure is stabilized, the inlet valve is closed; and the pressure is
maintained for 20 min.
