FUEL CELL

PURPOSE:To obtain a fuel cell having small size, long life, and high performance by filling a porous body, in which an electrolyte for reserve is retained, in a space formed by the surface, which is not faced to an electrode, of a corrugated current collecting plate and a separator. CONSTITUTION:When the electrolyte in an electrolyte plate 1 is in short supply, the electrolyte in an electrolyte reservoir 11 is supplied to the electrolyte plate 1 from upper and lower directions through electrolyte supply holes 12, and an anode 2 or a cathode 3. The consumption of the electrolyte in the electrolyte plate 1 is supplemented and the life of a cell is increased. Since the electrolyte reservoir 11 is conductive, internal resistance in the cell is decreased and cell performance is increased. In addition, since the need for installing a reserve space separately is eliminated, a fuel cell is made compact.
