PURPOSE:To make the surface pressure which applies between a separator and electrode plates uniform when a plurality of cell units are stacked and fastened by forming an outer plate of a separator using one sheet of a thin metal sheet, and forming a plurality of through holes with small diameter for supplying a gas to electrode plates in the center part of the outer plate. CONSTITUTION:In a cell unit 1, electrode plates 3, 4 which are a negative and a positive pole with almost the same size are put in both sides of an electrolytic plate 2 and further separators 5 larger than the electrolyte plate 2 and the electrode plates 3, 4 are put in both sides. An outer plate 7 of the separator 5 is one sheet of a metal thin sheet and a large number of through holes 11 with small diameter in the center part and an edge part 12 in the outside of the through holes are formed unitedly so that the whole plate is kept well flat. Consequently, even if there is a gap between the outer plate 7 of the separator 5 and each of electrode plates 3, 4, a large number of cell units are stacked and fastened with uniform plane pressure. |
