Abstract: 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.
