The fuel cell system including a rupture part between hydrogen supply valve and hydrogen shut-off valve

摘要

An object of the present invention is to provide a connection structure of a hydrogen supply valve and a hydrogen shut-off valve which minimizes piping damage in a hydrogen supply system and can prevent leakage of hydrogen. The present invention relates to a fuel cell system including a hydrogen shut-off valve and a hydrogen supply valve connected to the hydrogen shut-off valve. The fuel cell system includes a holder capable of receiving the hydrogen supply valve, and the holder includes a rupture portion formed at one point between the hydrogen supply valve and the hydrogen shut-off valve. The hydrogen shut-off valve may be accommodated in an extended end of the holder and the hydrogen shut-off valve is disconnected from the hydrogen supply valve as the rupture portion is cut by an external impact.
