燃料电池汽车氢系统泄放安全研究
Research on release safety of on-board hydrogen system in fuel cell vehicle
摘要
Abstract
In view of the abnormal damage of TPRD in hydrogen system of hydrogen fuel cell vehicles in winter,which affects the sealing and strength of the release system,and seriously endangers release safety of hydrogen,the effects of ice swelling of entering water of the on-board hydrogen system release pipeline were analyzed systematically by designing frozen heave resistance test for TPRD.The test results show that after water enters the discharge pipeline of the on-board hydrogen system,the frost heave stress generated during the repeated"freezing-thawing"cycle causes the TPRD of the two sets of bottle mouth combination valves used in the test to be accidentally activated,and both failed the anti-frost heave test.Among them,the glass bubble TPRD was discharged according to the preset channel,and the fusible alloy TPRD was not discharged according to the preset channel,which seriously affected the safety of hydrogen discharge.Therefore,in the future,more attention should be paid to the waterproof and drainage design of the release pipeline to avoid hydrogen-related safety accidents due to water injection.关键词
