PURPOSE:To prevent a local cell from being formed and reduce the loss of an electrolyte and local corrosion by providing electrolyte plates for wet sealing and electrolyte plates for each electrode section face to face for individual gas passage holes at the periphery of a separator. CONSTITUTION:Wet sealing electrolyte plates 1b of passage holes 5, 7 feeding the oxidation gas and wet sealing electrolyte plates 1b of passage holes 6, 8 feeding the fuel gas are independently provided separately from each other at the periphery of each cell, and the wet sealing electrolyte plates lb of the passage holes are independent from electrolyte plates 1a for electrode sections. Thereby, even if the wet sealing electrolyte plates 1b of the passage holes 5, 7 of the oxidation gas and the wet sealing electrolyte plates 1b of the passage holes 6, 8 of the fuel gas are brought into contact with a separator 4 and the carbonate in the electrolyte plates 1b reaches the separator 4, no positive electrode section and negative electrode section are generated on the surface of the separator 4 to cause a short circuit. Accordingly, a local cell is prevented from being formed on the surface of the separator 4. |
