燃料电池汽车氢气消耗量测量方法研究进展

Development of Hydrogen Consumption Measurement Methods for Fuel Cell Vehicles

经济性在汽车测评中是一个十分重要的评价指标。对于燃料电池汽车来说,氢气消耗量与其经济性紧密相关。本文对国内外燃料电池汽车氢气消耗量的测量方法进行了综述,研究表明:国内外现行标准均采用了外部供氢测量方法,包括:温度压力法、质量法和流量法,其具有测量精度高,操作性强等优点。而内部供氢测量法包括氧平衡法、改进的氢氧平衡法尚需进一步试验验证其测量精度,后续可对其多多关注。

Economy is a very important evaluation index in automobile evaluation. For fuel cell vehicles, hydrogen consumption is closely related to its economy. In this study, the measurement methods of hydrogen consumption of fuel cell vehicles are reviewed. The research shows that the current standards at home and abroad adopt the measurement methods of external hydrogen supply, including temperature and pressure method, mass method and flow method, which have the advantages of high measurement accuracy and strong operability. However, the internal hydrogen supply measurement methods include oxygen balance method and improved hydrogen oxygen balance method. Further experiments are needed to verify the measurement accuracy, and more attention can be paid to it in the future.
