  • Model based detection of hydrogen leaks in a fuel cell stack

    fuel cell stacks there is always an accepted leak level as it is impossible to completely seal the cells. An increase in leak due to rupture of seals can be the cause of a critical concentration of H2 to form which in turn can lead to an explosion. The standard solution to hydrogen leak detection is toFile Size: 220KB
