摘要： A cooling plate in which flow channels are modified to reduce temperature differences between portions of the cooling plate and provide for more uniform heat distribution within a heat generator. The flow channels of the cooling plate are formed such that a central portion of the flow channels has a greater volume than the end portions near an inlet and an outlet so that the amount of cooling water that is contained in the central portion at any one time is larger than either of the end portions near the inlet and the outlet. Likelihood of thermal deformation of the cooling plate due to thermal stress is decreased, and stability of performance of the fuel cell is increased.

摘要： A fuel cell stack having an improved sealing structure of a cooling plate in which the cooling plates therein each have a coolant flow channel through which a coolant flows to remove heat from the fuel cell stack and a groove that surrounds the coolant flow channel, and a sealing member disposed in the groove to prevent coolant leakage. The sealing member has a compression rate of 18 to 30%, as the compression rate being ((a thickness of the sealing member−a height of the groove)/the thickness of the sealing member)×100. Such a fuel cell stack may maintain operation for a long time without the need of supplementing the coolant.

摘要： A fuel cell stack having a sealing structure for sealing gasses and cooling water. The sealing structure is also electrically insulative. The fuel cell stack includes O-ring beds that are combined to the gas flow plates and through which liquid flow holes cooling water passes, gaskets that surround the gas flow plate to prevent the leakage of the gasses, and O-rings that surround the flow channels of the cooling plates and the O-ring beds to prevent the leakage of the cooling water. Manufacturing costs of the sealing structure are reduced while production efficiency is increased.
