Fuel cell shutdown system

The invention relates to a fuel cell shut-off valve (36) having a valve shut-off body (5) which can be moved electromagnetically from a first position into a second position by energizing an electric coil (10) in order to close or release at least one media path of a fuel cell. In order to optimize...

Beschreibung
Zusammenfassung:	The invention relates to a fuel cell shut-off valve (36) having a valve shut-off body (5) which can be moved electromagnetically from a first position into a second position by energizing an electric coil (10) in order to close or release at least one media path of a fuel cell. In order to optimize the operation of the fuel cell system, the fuel cell shut-off valve (36) comprises two permanent magnets (13, 14), by means of which the valve shut-off body (5) can be held both in the first position and in the second position in the current-free state of the electrical coil (10). 本发明涉及一种燃料电池关闭阀(36)，具有阀关闭体(5)，所述阀关闭体能够通过电线圈(10)的通电以电磁的方式从第一位态运动到第二位态中，以便封闭或释放燃料电池的至少一个介质通路。为了优化燃料电池系统的运行，燃料电池关闭阀(36)包括两个永磁体(13、14)，所述阀关闭体(5)通过所述永磁体在所述电线圈(10)的无电流的状态中既能够保持在所述第一位态中也能够保持在所述第二位态中。
