ABSTRACT:
A fuel cell in which the sealed portions formed at the peripheral edges of gas flow passages of a gas separating plate are turned so that they have a U-shaped cross section in the direction of the lamination so as to provide for elasticity. A filling member is filled in the interior of the sealed portions. This gas separating plate is used to respectively form gas flow passages through which different gas fluids are caused to flow so that they are electrochemically reacted in a pair of electrode reacting portions disposed with an electrolyte layer being interposed therebetween. In consequence, the sealed portions provided at the peripheral edges of the gas flow passages deform in accordance with the creep caused in the electrode reacting portions. This enables a balanced, adequate bearing pressure to be kept applied to the electrode reacting portions and the sealed portions, thereby enabling the fuel cell to be operated in an excellent gas sealed state for a long time.
