如果普通大众要使用氢作为汽车燃料，消费者必须能够以与传统液体和气体燃料相同的信心和相当的风险来处理氢。如果氢气作为高压气体储存和使用，则必须考虑车辆加油环境中泄漏的喷射释放相关的危险，因为在密闭或拥挤的区域中喷射释放会产生爆炸危险。由于对爆炸危险的认识不足，因此开展了一项研究，以更好地了解与氢燃料汽车加油系统高压泄漏相关的潜在爆炸危险后果。本文描述了用虚拟车辆和加油机单元来模拟加油站拥堵的实验。介绍了5.4 m × 6.0 m × 2.5 m预混氢空气云点火实验和压力高达40 MPa （400 bar）的氢喷射。讨论了导致最大超压的条件，并从中得出了总体结论。
If the general public is to use hydrogen as a vehicle fuel, customers must be able to handle hydrogen with the same degree of confidence, and with comparable risk, as conventional liquid and gaseous fuels. The hazards associated with jet releases from leaks in a vehicle-refuelling environment must be considered if hydrogen is stored and used as a high-pressure gas since a jet release in a confined or congested area can create an explosion hazard. As there was insufficient knowledge of the explosion hazards, a study was initiated to gain a better understanding of the potential explosion hazard consequences associated with high-pressure leaks from hydrogen vehicle refuelling systems. This paper describes the experiments with a dummy vehicle and dispenser units to represent refuelling station congestion. Experiments with ignition of premixed 5.4 m × 6.0 m × 2.5 m hydrogen–air clouds and hydrogen jet releases up to 40 MPa (400 bar) pressure are described. The results are discussed in terms of the conditions leading to the greatest overpressures and overall conclusions are made from these.
