Zusammenfassung:	PURPOSE: An end plate for fuel cell stack is provided to improve the degradation of the fuel cell stack resulted from corrosion by working fluid, and to have good corrosion resistance and clamping force. CONSTITUTION: An end plate (100) comprises an end plate main body (120) and an anti-corrosion stiffener (140). The end plate main body, which is arranged in the respective channel area (CA) corresponding to the channel part of metal separation plate and both edge parts facing to the channel area, has a manifold area (MA) corresponding to the manifold of the metal separation plate. Storing grooves are formed respectively in the manifold areas of both sides. The anti-corrosion stiffener, which is combined in order to be accepted within the storing grooves, prevents corrosion by the working fluid flowing to the manifold area.
