✦ Synopsis

Abshaet -The paper examines the influence of the relative electric conductivity of the solution and matrix phases on the potential distribution in flow-through porous electrodes working under limiting current conditions. The solution giving the potential distribution is deduced and is experimentally tested for packed bed electrodes of graphite microspheres using the reduction of ferricyanide ions as the electrochemical reaction. A satisfactory agreement between theory and experiment is observed.
