Abstract
The invention is a dampening device for use in a vertically disposed electrochemical cell unit of the type at least having: (a) a peripheral flange which defines at least one electrode chamber, said peripheral flange having a upper, substantially horizontally disposed flange portion, a lower substantially horizontally disposed flange portion, and two disposed side flange portions; and (b) at least one outlet port passing through the upper horizontally disposed flange portion or through one of the two vertical side flange portions or through the lower flange portion and connecting the exterior of the cell with the electrode chamber. The dampening device is an elongated, hollow duct positioned across at least a portion of the top of the electrode chamber adjacent to the upper, horizontally disposed flange portion, said duct being in fluid flow communication with said electrode chamber and with said outlet port(s), wherein the duct has at least one opening near its top which connects the interior of the duct with the electrode chamber, wherein said opening(s) has a total cross sectional area less than or equal to the greatest internal cross sectional area of the duct. The invention includes an electrochemical cell containing the dampening device.
