A solenoid-operated valve for use with fuel cells has a valve housing made of aluminum, for example and having first through third heating medium passages defined therein. A valve seat disposed in and fastened to the valve housing is made of stainless steel, for example. A valve head has a disk which can be seated on and unseated off a valve seat member of a valve seat. The valve head is coupled by threaded surfaces to the distal end of a movable member which is displaceable when a solenoid is energized. The movable member is made of a magnetic metallic material, and the valve head is made of a corrosion-resistant metallic material such as stainless steel or the like, for example.

What is claimed is: 1. A solenoid-operated valve for discharging a reaction gas and/or residual water from fuel cells, comprising: a valve housing having an inlet port for introducing the reaction gas and/or residual water and an outlet port for discharging the reaction gas and/or residual water introduced from said inlet port, said valve housing having a communication chamber defined therein between said inlet port and said outlet port; a valve seat disposed in said communication chamber and coupled to said valve housing; a solenoid housing coupled to said valve housing; a solenoid disposed in said solenoid housing for being energized by an electric current supplied thereto; a fixing member disposed in said solenoid; a movable member having an end facing said fixing member, wherein said movable member has a first inner hole defined axially therein and a second inner hole defined diametrically therein in communication with said first inner hole, said movable member being displaceable toward or away from said fixing member when said solenoid is energized; a valve head coupled to an opposite end of said movable member, wherein said valve head has a first inner hole defined axially therein in communication with said first inner hole of the movable member and a second inner hole defined diametrically therein in communication with said second inner hole of the movable member and said first inner hole of the valve head, said valve head being seatable on or away from said valve seat when said movable member is displaced; and a guide member disposed in said valve housing and said solenoid and having a guide hole, said movable member being inserted in said guide hole, said guide member having an engaging portion for limiting said valve head against displacement in a direction away from said valve seat. 2. A solenoid-operated valve according to claim 1, wherein said movable member and said valve head are coupled to each other by threaded surfaces thereof. 3. A solenoid-operated valve according to claim 1, wherein said valve housing is made of aluminum or aluminum alloy, and said valve seat is made of a material different from said valve housing. 4. A solenoid-operated valve according to claim 3, wherein said valve seat is made of stainless steel. 5. A solenoid-operated valve according to claim 1, wherein said valve housing has a heating medium passage defined therein for passage of a heating medium therethrough. 6. A solenoid-operated valve according to claim 5, wherein said valve housing has a plurality of heating medium passages defined therein, said heating medium passages extending perpendicularly to each other and surrounding said communication chamber. 7. A solenoid-operated valve according to claim 6, wherein one of said heating medium passages has an opening at an end thereof which is open at an end face of said valve housing, said opening being closed by a closure member. 8. A solenoid-operated valve according to claim 1, wherein said valve head and said movable member are made of different materials. 9. A solenoid-operated valve according to claim 8, wherein said valve head is made of stainless steel. 10. A solenoid-operated valve according to claim 1, further comprising: a first sheet mounted on said valve head, said first sheet being made of an elastic material and disposed in a position to contact said valve seat when said valve head is seated on said valve seat; and a second sheet mounted on said valve head, said second sheet being made of an elastic material and disposed in a position to contact said engaging portion of said guide member. 11. A solenoid-operated valve according to claim 10, wherein said valve head has first and second mount grooves defined therein, said first sheet and said second sheet being mounted respectively in said first and second mount grooves, said first sheet and said second sheet being integrally joined to each other by a joint sheet made of an elastic material and filling a communication hole defined in said valve head and communicating between said first and second mount grooves. 12. A solenoid-operated valve according to claim 1, further comprising a filter mounted in said inlet port. 13. A solenoid-operated valve according to claim 1, wherein said guide member has an outside diameter which is substantially the same as an inside diameter of said communication chamber. 14. A solenoid-operated valve according to claim 1, wherein said valve seat and said valve housing are coupled to each other by bolts. 15. A solenoid-operated valve according to claim 1, wherein said movable member is of a cylindrical shape.
