The present invention provides a sealing structure of a sealing portion for maintaining the airtightness of a coolant passage in two stacked separators of a fuel cell, wherein a groove in which an adhesive is to be filled is formed on a surface of one of two separators, and dam portions are formed on both sides of the groove to prevent the adhesive applied in the groove from overflowing into a connection passage and a coolant passage. Accordingly, the adhesive overflowing from the groove when the two separators are bonded to each other by applying a pressure is collected in the dam portions to form three sealing lines, thus improving the airtightness of the sealing portion. Moreover, it is possible to solve the problem that the performance of the fuel cell stack is deteriorated when an antifreeze/coolant leaks from the coolant passage to an MEA, in which the fuel cell reaction takes place, or the leaking coolant contaminates a catalyst of the MEA.
