N2 - Analytical expressions quantifying the transport and kinetics in polymer-modified electrodes containing a homogeneous distribution of spherical microparticulate catalysts are presented. In particular the dependence of the flux on the number of catalytic particles per unit volume, the layer thickness, the substrate and mediator concentrations, the particle radius and the electrode potential are outlined for the situation of conducting polymer catalyst and ionomer-mediator-catalyst composites. A strategy for optimising the electrocatalytic behaviour of these multicomponent microheterogeneous systems is also outlined.
