PURPOSE:To improve reliability and increase life by bringing a porous material into contact with a plurarity of plate groups which are inserted into the same cell over a reinforcing partition. CONSTITUTION:A plate-shaped porous material 14 is inserted into the same cell of a container divided with a reinforcing partition 13 through which gas is permeable so as to contact each plate group 12. The porous material 14 consists of material same as a separator comprising fine glass fibers. The electrolyte volume and gas absorbing ability in each plate group become uniform, and capacity scattering in every plate group and abnormal corrosion of positive grid can be prevented. |
