PURPOSE:To readily supply an electrolyte to a matrix from the outside of a battery and provide a cell having stable performance and long life by passing through a path connecting a separator, a fuel electrode, a matrix, and an oxidizing agent electrode with an electrolyte reservoir installed in the edge of the separator by an electrolyte supply groove installed in the separator. CONSTITUTION:When an electrolyte is supplied, an electrolyte is filled in an electrolyte path 9 and overflowed in an electrolyte reservoir 8 of each cell. The electrolyte overflowed in the electrolyte reservoir 8 enters an electrolyte supply groove 6 and is supplied to a matrix 1 through an electrolyte connecting path 10. To prevent wetting of a fuel electrode base material 2a by the electrolyte, the fuel electrode base material 2a is coated with polytetrafluoroethylene to make it water repellent. When the electrolyte is supplied to the fuel electrode base material 2a by electrolyte supply pressure, the number of the stacked cells which are an electrolyte supply unit are decreased to reduce electrolyte supply pressure. After the electrolyte is filled in electrolyte supply groove 6, the electrolyte is removed from the electrolyte path 9 to prevent liquid short circuit by the electrolyte. |
