摘要： PURPOSE:To prevent deterioration of a sealant caused by contact with concentrated phosphoric acid by installing a projection in parallel to the sealant in the lowerpart, where a supporting plate of a fuel cell stack is fit to a container through the sealant, of a reacting gas supply and exhaust container. CONSTITUTION:Interconnectors 2 are placed on both sides of a unit cell 1 and they are stacked and fixed with supporting plates 5 from the upper and lower directions. A reacting gas supply and exhaust container 7 is fit to the supporting plates 5 through a sealant 6 such as fluorine rubber to form a fuel cell. A reacting gas supply and exhaust container 11 having a projection 12 installed in parallel to the sealant 6 in the inner lower part on the container to form a reservoir, and having an exhausting hole 13 is used instead of the reacting gas supply and exhaust container 7. Condensed water inside the container 11 is stored and exhausted adequately. Therefore, deterioration of the sealant 6 caused by phosphoric acid contained in the condensed water is surely prevented.
