PURPOSE:To accurately prevent the corrosion and deterioration of the base material of a manifold that supplies gas to a preset element battery laminate body by covering the inner surface of the gas contact with preset materials. CONSTITUTION:The inner surface of the gas contact of mainfolds 2-5 that supply fuel gas and oxidizing agent gas to an element battery laminate body 1 that uses phosphoric acid as the electrolyte through piping 7 is covered with a zinc plate 8 and such made of sacrificial materials that are easy to react to phosphoric acid and make the phosphoric acid harmless. As a result, the corrosion and deterioration of the base metal of the manifolds 2-5 are prevented with accuracy. |
