Electrochemical cell having an inflatable member

摘要

A conductive inflatable member is provided in an electrochemical cell between an electrode and a current for providing uniform contact pressure, and thus uniform electrical contact between the electrode and the current bus. The inflatable member may comprise a pair of flexible plates, where one plate is thinner than the other plate. The cell of the present invention is particularly useful in converting anhydrous hydrogen halide directly to essentially dry halogen gas, such as anhydrous hydrogen chloride to dry chlorine gas, or in converting aqueous hydrogen halide, such as aqueous hydrogen chloride, to wet chlorine gas.
