Abstract: A cooling plate with a sealing structure and a fuel cell stack employing the same are provided to maximize sealing efficiency when the compressive modulus of a sealing member is within 18~30% and the surface illumination of an inner wall is in a range of Rmax 0.11-14micron. A cooling plate(200) comprises: a coolant channel through which a refrigerant flows; and a groove(201) in which a sealing member(300) with compressive modulus of 18~30% is inserted and which surrounds the coolant channel. A fuel cell stack consists of: a cell in which an electrogeneration reaction takes places; the cooling plate with the coolant channel and the groove; and the sealing member which is inserted into the groove in order to prevent the leakage of the refrigerant. The sealing member has 18-30% of compressive modulus defined as (the thickness of the sealing member - the height of the groove)/the thickness of the sealing member * 100.

Abstract: A stack for a fuel cell is provided to perform the cooling of reaction heat while progressing smooth electricity generating-reaction and to progress initial increase of temperature rapidly. A stack for a fuel cell comprises a membrane-electrode assembly(120) laminated with an anode(121), an electrolyte film(123) and a cathode(122); a bipolar plate(110); and a cooling plate(130). The bipolar plate comprises reaction channels(112a) where fluid supplied to the anode and cathode flows into; and many internal manifolds formed at an adjacent position which is not connected directly with the reaction channels in order to pass a refrigerant.
