Abstract: To fight against abnormal climate change and improve environment friendly development, the new energy vehicles enter a new stage of rapid growth in China. As an important direction of new energy vehicle, fuel cell vehicle is strongly supported by national and local government. Fuel cell stack is one of the core components of fuel cell vehicle, whose environmental adaptability will significantly influence the performance of the vehicle. Therefore, the environmental adaptability test of fuel cell stack is essential for product development. However, currently there is no national standard for the environmental adaptability test of fuel cell stack. This paper studies the environmental adaptability test of fuel cell stack based on its working environment conditions and application scenarios, and puts forward the design concept of the environmental adaptability test method of fuel cell stack, so as to provide some reference for the industry to arrange the environmental adaptability test plan of fuel cell stack.

Key words: Fuel cell vehicle; Fuel cell stack; Environmental adaptation

摘要： 为应对气候变化，推动绿色发展，近年来我国新能源汽车进入加速发展新阶段。燃料 电池汽车是新能源汽车的重要发展方向，得到了国家和地方政府的大力支持。燃料电池电堆 作为核心零部件之一，其环境适应能力将直接影响整车的性能，因此，进行电堆环境适应性 试验是产品开发必不可少的环节。但是目前我国针对车用燃料电池电堆的环境适应性试验还 未形成统一标准，因此，文章结合车用燃料电池电堆工作环境条件和应用场景，对其环境适 应性试验进行了研究，提出了电堆环境适应性试验方法的设计思路，以期为业内人士制定电 堆环境适应性试验方案提供一定参考。
