Abstract: As the power core of fuel cell vehicles, fuel cell engines require high-speed rotation of the air compressor and the operation of the hydrogen sub cycle system to ensure continuous power generation of the fuel cell stack during operation. This paper introduces two test methods for noise, vibration and harshness (NVH) performance of fuel cell engines during operation, based on simple noise testing and semianechoic chamber noise testing methods, which can provide reference for NVH test methods for fuel cell engines in the industry at present.

Key words: Fuel cell engines; NVH performance; Test methods

摘要： 燃料电池发动机作为燃料电池汽车的动力核心，在运行过程中需要空压机高速旋转和 氢气子循环系统工作保证燃料电池堆持续发电。文章基于简易噪声测试和半消声室噪声测试 方法，介绍了两种测试燃料电池发动机工作时噪声、振动与声振粗糙度（NVH）性能的试验 方法，为现阶段行业内针对燃料电池发动机的 NVH 试验方法提供借鉴。
