PURPOSE:To maintain the steady performance of an electrolyte plate over a long period of time by installing an electrolyte reservoir in the circumference of a fuel cell, supplementing the electrolyte in the reservoir to an electrolyte plate during shortage, and storing the electrolyte in the reservoir during excess. CONSTITUTION:An electrolyte reservoir 8 having an L-shaped cross section is installed at the end of a seaprator 2 as electrolyte retaining structure. When the electrolyte in an electrolyte plate 5 is consumed and cell performance is decreased, by increasing the pressure P1 in a manifold 7 than the pressure P2 in the electrolyte plate 5, an electrolyte 9 in the reservoir 8 penetrates in an arrow direction from the end of the electrolyte plate 5 and the electrolyte 9 is supplemented to the electrolyte plate 5. When supply of reaction gas is stopped in starting or in discontinuing of power generation, molten electrolyte directly flows out from an end plate 1 because of no consumption of electrolyte. This electrolyte is stored in the reservoir 8, and flow out to the outside is prevented. Therefore, corrosion of the end of the separator 2 caused by electrolyte is prevented. |
