摘　　要：针对“清能3号”燃料电池电动汽车在一次国际性比赛上所给出的燃料经济性指标结果,比较了用van derW aa ls方程和氢气压缩系数计算氢气质量的两种方法。通过计算得出了合理的燃料经济性指标,指出赛会组织者应用van derW aa ls方程计算燃料经济性指标有误,同时建议使用压缩系数法。给出了由气体压强p、体积V和温度T计算气体质量m的解析解,列出了在压强、体积采用不同单位时,对应的普适气体常数R和改正项a、b的数值,为求解van derW aa ls方程提供了方便。The fuel economy of the QingNeng 3 fuel cell vehicle was corrected using two methods for calculating the hydrogen consumption based on the van der Waals equation and the compression coefficient. Rational fuel economy results obtained with illustration of the mistakes made in previous calculations using the van der Waals equation. The compression coefficient is recommended for calculating fuel economy indexes. Analytical calculations of the gas mass, m, are based on the pressure, p, volume, V, and temperature, T, in the van der Waals equation with the correction coefficients, a and b, given as functions of p and V with different units to improve the hydrogen consumption calculation accuracy.
