Abstract

Abstract A metallic porous mass immersed in an electrolyte where an electric current flows, can behave as a bipolar electrode giving rise to electrochemical reactions. If this system separates two different electrolyte solutions and some soluble species are formed, they can diffuse through the porous mass and participate in some chemical reaction characteristic of one of the electrolytes. Such electrochemical system can be indicated as bipolar porous electrode with internal mass transfer and can be employed in practical applications to prevent the migration of unwanted ionic species from one compartment to the other of an electrolysis cell.
