Solenoid-operated valve for fuel cells

A solenoid-operated valve for discharging a reaction gas from a fuel cell, comprising:

• a valve housing having a first port for introducing the reaction gas and a second port for discharging the reaction gas introduced from said first port;
• a solenoid unit disposed in a casing joined to said valve housing, said solenoid unit being energizable by a current;
• a movable core disposed in facing relation to a fixed core disposed in said solenoid unit and displaceable axially when said solenoid unit is energized;
• a shaft engaging said movable core and axially displaceable in unison with said movable core;
• a valve head disposed in said valve housing and engaging an end of said shaft;
• a valve seat, said valve head being seatable on and unseatable from said valve seat when said shaft is displaced;
• a diaphragm disposed between said valve housing and said casing and attached to said shaft, said diaphragm being flexible in response to displacement of said shaft;
• and
• an elastic member disposed between said movable core and said fixed core.
