基于质子交换膜燃料电池车用氢气产品质量标准GB/T 37244的探讨. (Chinese)

Objective The proton exchange membrane fuel cell vehicle plays an important role as a key scenario of hydrogen energy application. The impurity content limits and analytical methods involved in the current product standard GB/T 37244-2018 Fuel specification for proton exchange membrane fuel cell vehicles-Hydrogen are discussed. Methods The evolution process of hydrogen fuel product quality standards in China is reviewed, the relevant hydrogen product indicators and analysis method standards at home and abroad are compared, and the impurities derived from the current situation of hydrogen source in China and the actual demand analysis are investigated. Results The composition requirements of key impurities and other impurities in hydrogen fuel should be improved according to the actual research results. It is suggested that using the combination of key component inspection, type inspection and factory inspection to analyze the impurities. Conclusions Under the premise of meeting China's hydrogen fuel energy endowment and international standards ISO 14687:2019 Hydrogen fuel quality-Product specification, the current product quality standards should be revised, and the standard system and traceability chain of hydrogen fuel quality analysis methods should be improved to ensure the accuracy and efficiency of the analysis.
