为了确定与加氢站相关的安全问题，考虑到日本和美国的法规，对这些加氢站发生的事故进行了分析。日本和美国的设备和管道主体损坏、断裂造成的泄漏，主要是由于设计失误，即计划不周的疲劳造成的。考虑到这些国家目前发生的事件，设计中充分考虑使用环境非常重要。日本的法兰、阀门、密封件的泄漏主要是由螺纹连接造成的。如果日本加氢站要使用焊接接头，应获取焊接件的强度数据并减少管道厚度。在日本和美国，由于外部影响等其他因素造成的泄漏主要是人为失误造成的。为了实现自助加氢站，应制定安全措施，防止燃料电池汽车用户的人为错误。
To identify the safety issues associated with hydrogen fueling stations, incidents at such stations in Japan and the USA were analyzed considering the regulations in these countries. Leakage due to the damage and fracture of main bodies of apparatuses and pipes in Japan and the USA is mainly caused by design error, that is, poorly planned fatigue. Considering the present incidents in these countries, adequate consideration of the usage environment in the design is very important. Leakage from flanges, valves, and seals in Japan is mainly caused by screw joints. If welded joints are to be used in hydrogen fueling stations in Japan, strength data for welded parts should be obtained and pipe thicknesses should be reduced. Leakage due to other factors, e.g., external impact, in Japan and the USA is mainly caused by human error. To realize self-serviced hydrogen fueling stations, safety measures should be developed to prevent human error by fuel cell vehicle users.
