However, there are some limits under operation; the vibration tolerance is much lower than internal combustion engine. Although fuel cell stack operates with few moving parts and almost no vibration, and the vibration from road could still cause damage to the fuel cell stack. In this study, a combination of fuel cell hybrid scooter vibrating simulation analysis and suspension system adjustments were proposed to reduce the road impact acceleration on fuel cell stack. According to the fuel cell stack sustainable vibration range, a CAE software ADAMS is added to do sensitivity analysis and suspension system design to reduce the vibrating acceleration. In the analysis result, the vibrating acceleration and dynamic performance for the scooter could be successfully simulated under different riding speed, and successfully be reduced by using spring – damping system. The experiments verified CAE simulating results and show a high coherence, also successful reducing the vibrating acceleration under 3g. By using the design method proposed in this research, a fuel cell scooter could also keep the dynamic performance and achieve fuel cell stack protection target without changing conventional riding custom.
