Patent ID: 7416807

Claim:
A fuel cell comprising: an electrolyte membrane; a pair of electrodes disposed respectively on both faces of said electrolyte membrane; a pair of conductive separator plates which sandwich said electrodes and have gas flow channels for supplying reactive gases to said electrodes; and a pair of sealing means which sandwich said electrolyte membrane between said pair of separator plates and maintain hermeticity between said pair of electrodes and said pair of separator plates, wherein said pair of sealing means is constituted by combination of a flat sealing member having a flat portion in flat contact with said electrolyte membrane and of a linear sealing member having a rib in linear contact with said electrolyte membrane, wherein said rib is curved to the side of said electrode, and said rib is warped and bent to the side of said pair of electrodes when said electrolyte membrane, said pair of electrodes and said pair of separator plates are stacked to be clamped.
