车载液氢储存系统国际标准比较分析

Comparative Analysis of International Standards for Vehicle Liquid Hydrogen Storage Systems

与传统氢气相比,液氢的能量密度更高,储存压力更低。目前,国外已有采用液氢作为燃料的成功案例。从质量、体积以及储氢密度考虑,车载液氢技术更接近实用化目标要求。美国及欧洲一些国家已开展车载液氢的相关研究,并制定了一些标准。对GTR 13:2013 “Global Technical Regulation on Hydrogen and Fuel Cell Vehicles”、 SAE J2579:2013 “Standard for Fuel Systems in Fuel Cell and Other Hydrogen Vehicles”中规定的液氢储存系统的鉴定设计要求及试验程序进行了比对,可为国内液氢储存系统标准的制定提供参考。

Compared to conventional hydrogen,liquid hydrogen has a higher energy density and lower storage pressure. At present,there have been successful cases of using liquid hydrogen as a fuel in foreign countries. The vehicle liquid hydrogen technology is closer to the practical target requirements when the mass,volume and hydrogen storage density were considered. Research on vehicle liquid hydrogen was carried out and some standards were formulated in the United States and some European countries. The qualification design requirements and test procedures of liquid hydrogen storage systems specified in GTR 13: 2013 “Global Technical Regulation on Hydrogen and Fuel Cell Vehicles” and SAE J2579: 2013 “Standard for Fuel Systems in Fuel Cell and Other Hydrogen Vehicles” were compared,and a reference for the formulation of standards for liquid hydrogen storage systems in China was provided.
