摘要
燃料电池汽车车载储氢瓶的安全性一直是全社会关注的热点问题,其中氢循环充放试验是检验车载储氢瓶的抗疲劳、瓶口泄漏及内胆材料(IV型瓶)氢渗能力的重要手段。目前国际上关于氢循环试验的标准主要有两个,分别是由联合国世界车辆法规协调论坛制定的GTR No.13和由国际标准化组织制定的ISO 19881,国内标准则是由国家标准化管理委员会制定的GB/T 35544。本文介绍了这些标准在氢循环试验层面的内容,比较了其在试验对象、循环方法、卸放速率、验收标准等方面的异同之处。在此基础上,本文讨论了加注时长、卸放速率两个关键问题对储氢瓶温度、寿命的影响,指出了国内外标准在此存在的不足之处。最后,本文提出了相应的建议,以供氢循环试验的实施作参考。
The safety of fuel cell vehicle’s hydrogen storage tanks raises wide concerns in the society.The hydrogen cycling test is an important method to check tank fatigue,boss leakage and liner permeation.Nowadays there are two standards concerning hydrogen cycling test.They are GTR No.13 developed by World Forum for Harmonization of Vehicle Regulation and ISO 19881 developed by International Organization for Standardization.The domestic standard is GB/T 35544 developed by Standardization Administration of China.This paper introduces the contents related to hydrogen cycling test in these standards.Also,it compares their similarities and differences in the aspects of test object,cycling procedure,depressurization rate and acceptance criteria.Based on this,it discusses impacts of refueling time and depressurization rate on hydrogen storage tank’s temperature and life.Furthermore,it points out the deficiencies of these standards.Finally,it gives corresponding suggestions when deploying the hydrogen cycling test.
