A one-dimensional model of the current and potential distribution in a porous electrode, which accounts for internal limitations of mass transport is presented. The electrode kinetics of the reaction are described by the Tafel approximation and the mass transport limitations are described by a mass transfer coefficient. The model is solved analytically to give a convenient algebraic equation to predict the influence of electrode parameters, such as conductivity, thickness and specific surface area on electrode polarisation. The model can also predict the influence of reactant concentration and internal mass transport on the electrode polarisation behaviour. The predicted electrode polarization is in agreement with that observed for a porous platinum based anode. © 2004 Elsevier B.V. All rights reserved.
