PROBLEM TO BE SOLVED: To prevent the performance deterioration by supplying a carbonate from an electrolyte reservoir to an electrode or an electrolyte layer, in response to consumption of the carbonate in the electrode or the electrolyte layer. SOLUTION: An electrolyte reservoir 100 for replenishing an electrolyte is arranged in a lower part of a wet seal part 6b in a separator plate 66 end part. The electrolyte reservoir 100 is composed of the first electrolyte reservoir 101 which is arranged to be in contact with an end part of an oxidant electrode 46, and the second electrolyte reservoir 102 layered to make contact with the first electrolyte reservoir 101, without making contacting with the oxidant electrode 46 and an electrolyte matrix 31. An average pore diameter in the first electrolyte reservoir 101 is formed smaller than the in the second electrolyte reservoir 102. |
