A simplified, one-dimensional, macroscopic model for porous electrode reactors with forced convection was experimentally verified. The mass-transferlimited reduction of ferricyanide ions was studied using porous graphite electrodes in a cell configuration having an upstream counterelectrode. Impedance characteristics of the electrode-electrolyte system were measured by the trafisient potentiostatic step method. An expression for the potential difference between upstream and downstream ends of an operating reactor was obtained based on the simplified macroscopic model. An experimental method was also developed for determining the efficiency of porous electrode systems from the variation of this potential difference with solution flow rate. In further work, new equations were derived that allow optimum linear flow rate and electrode length to be predicted for a porous electrode reactor operating at any desired efficiency. Predictions of a straight-pore model of porous electrodes are compared with those of the macroscopic model.

“…Exponent b reflects the hydrody namic mode of solution flow and can vary from 0.3 for a laminar flow to 0.8-1.0 for a turbulent flow. Experi mental data in the literature [18][19][20][21][22] In some works, e.g., in [23], it is suggested to calcu late the mass transport coefficient according to the formula containing the viscosity constant, diffusion coefficient, diameter of graphitized carbon fibers with deposited metal, and linear flow velocity. However, it is obvious that the effective diffusion coefficient [2], same as the mass transport coefficient, depends on the degree of mixing, i.e., also on the flow velocity and properties of the graphitized carbon material, which results in problems related to numeric calculations.…”

The work considers descriptions of electrode reactions in the context of their application as boundary conditions in solution of problems of calculation of processes in electrochemical reactions. Meth ods of setting polarization curve equations under changing conditions of occurrence of electrochemical reac tions are presented, in particular for the dependence of equilibrium potential and exchange current on the concentration of the electroactive component. The effect of hydrodynamic conditions on the polarization dependence of current density on potential is considered in a flow 3D electrode.
