Abstract

An electrochemical device includes a plurality of electrode assemblies that define a plurality of electrochemically active areas. A non- electrically conductive manifold includes a common manifold passage and a plurality of branch passages that extend , respectively ,between the electrochemically active areas and the common manifold passage. Each of the branch passages includes a first region and a second region that differ in surface area.
