车用燃料电池系统耐久性研究

燃料电池的耐久性是燃料电池汽车的关键技术问题，车用燃料电池寿命需要达到5000小时以上才能满足汽车应用要求. 作者基于车用燃料电池失效模式的研究，通过优化系统设计和改进系统控制策略等，开发出长寿命的HySYS-30车用燃料电池系统，并采用车用动态工况，对所开发的燃料电池系统进行了6000小时以上的耐久性测试，6000小时的性能衰减率仅为8.1%.

Durability Performance of the High-Power Fuel Cell System

Fuel cell durability is the crucial challenge in fuel cell vehicle, and the lifetime of more than 5000 hours is believed to be necessary for vehicle application. Few works on durability test of the full fuel cell system have been reported. In this work, the long lifetime HySYS-30 fuel cell system was developed in Sunrise Power based on the improved MEA durability and system control strategy. The durability performance of the system was investigated under vehicle duty cycle for more than 6000 hours, and only 8.1% performance loss was observed, implying that the durability of HySYS-30 fuel cell system could be more than 5000 hours.
