面向冬奥示范的新一代燃料电池系统技术突破

Technical Breakthrough of New Generation Fuel Cell System for Winter Olympics Application Environment

燃料电池汽车是新能源汽车的重要技术路线。针对2022冬奥应用环境,开展了燃料电池发动机系统高密度集成、耐久性管理和低温冷启动技术研究,提升其性能及低温环境适应性。车辆在张家口进行了近3年示范运营,经历了-20℃以下的低温环境,通过抽取样本信息,分析了燃料经济性、耐久性和可靠性。示范运营积累的经验和改进措施为2022冬奥会“氢能出行”服务及燃料电池汽车示范城市群项目实施打下基础。

Fuel cell vehicle is an important technical route of new energy vehicles. For the 2022 Winter Olympics application environment,the research on compact integration,durability management and cold-start of fuel cell engine system is carried out to improve its performance and low ambient temperature adaptability. Some fuel cell vehicles have been put into demonstrative operation in Zhangjiakou for nearly three years and have experienced low temperature environment below-20 ℃. Through sampled data,the economy,durability and reliability of fuel cell are analyzed. The experience and improvement measures accumulated in the demonstration operation have laid a foundation for the "hydrogen energy transportation" of 2022 Winter Olympics and the implementation of fuel cell vehicle city cluster demonstrative project.
