高压储氢气瓶作为氢燃料电池汽车的关键部件,其在火烧情况下的安全性能备受关注。《氢燃料电池汽车全球技术法规》首次提出的车用高压储氢气瓶局部火烧试验方法,将对我国氢燃料电池汽车的发展产生重大影响。该文在分析车用高压储氢气瓶整体火烧试验方法局限性的基础上,系统研究局部火烧试验方法提出的技术理由、主要内容和特点,指出我国车用高压储氢气瓶和压缩氢气储存系统发展面临的挑战,并针对我国正在制定的相关标准,提出若干建议。
As a key component of hydrogen fuel cell vehicles, high-pressure hydrogen storage cylinders have drawn much attention in the safety of fire. The first test of local fire test for high-pressure hydrogen storage gas cylinders for car by hydrogen fuel cell vehicle global technology regulation will have a significant impact on the development of hydrogen fuel cell vehicles in China. Based on the analysis of the limitations of the overall fire test method for automotive high pressure hydrogen storage cylinders, the paper systematically studies the technical reasons, main contents and characteristics of the local combustion tests, and points out that the development of high pressure hydrogen storage cylinders and compressed hydrogen storage systems Facing the challenges and put forward some proposals in light of the relevant standards that are being formulated in our country.
