GB/T 39132-2020Fuel cell electric vehicle engineering approval evaluation programme (English PDF)

1 Scope

China's national evaluation programme for the engineering approval of fuel cell electric vehicles. It specifies the terms and definitions, the implementation conditions, and the test items, methods and criteria. Engineering approval is the stage between a prototype that works and a product that can be sold: it establishes that the design is complete, that it performs as claimed, and that it is safe in the conditions it will meet. For a fuel cell vehicle the programme has to cover what is unlike a battery vehicle. Hydrogen is stored at seventy megapascals and leaks readily, so the tests address containment, detection and ventilation as much as performance. The fuel cell stack itself has a warm-up behaviour, a response lag and a freezing problem - the water it produces can freeze in the stack overnight and prevent starting. And refuelling is an interaction with an external system, which means the vehicle's communication with the dispenser is part of what has to be approved.

This Standard specifies implementation conditions, test items, test methods, judgment basis, test procedures and test report content for new product engineering approval evaluation program of fuel cell electric vehicle. This Standard is applicable to fuel cell electric vehicle that uses compressed gaseous hydrogen.
