Abstract
A fuel cell separator pair has first and second separators having front and back surfaces, a corrugated plate portion shaped in a wave form at the central portion, and a flat plate portion formed in the peripheral portion and surrounding the corrugated plate portion, wherein the corrugated plate portion of the front surface constitutes a reaction gas channel and the corrugated plate portion of the back surface constitutes a coolant channel. The back surfaces of the first and second separators are facing each other. The flat plate portions of the first and second separators are arranged on top of each other so as to be in contact with each other. The flat plate portion of the second separator protrudes toward the outside beyond the flat plate portion of the first separator. The fuel cell separator pair has a seal member (A) disposed on the flat plate portion of the front surface of the first separator, a seal member (B) disposed on the flat plate portion of the front surface of the second separator, and a seal member (C) disposed on the region protruding beyond the flat plate portion of the first separator in the flat plate portion of the back surface of the second separator.
