设计了一种用于便携式氢燃料电池的新型微型安全阀。该装置旨在防止燃料电池氢侧的过压。在其几乎打开的条件下对其密封性能进行了仔细的研究。泄漏率取决于密封表面的尺寸和垫圈的材料（碳氟化合物和聚对二甲苯膜）已使用氢气进行了研究。实验结果表明，小的密封表面导致小的泄漏率和聚对二甲苯膜容易损坏，导致重要的泄漏率。此外，它示出了通过减小阀喷嘴的宽度来减小装置的流动阻力。
A novel micro-safety valve for portable hydrogen fuel cells has been designed, fabricated and characterized. This device is intended to prevent over-pressure on the hydrogen side of the fuel cell. A careful study of its sealing properties has been conducted under conditions at which it is nearly open. The leakage rate depending on the size of the sealing surface and on the material of the gasket (fluorocarbon and parylene films) has been investigated using hydrogen gas. The experimental results show that small sealing surfaces lead to small leakage rates and that the parylene films are easily damaged, leading to important leakage rates. Moreover, it is shown that the resistance to flow of the device is diminished by reducing the width of the valve nozzle.
