Abstract A mathematical analogue based on an array of transmission lines has been used to predict the performance of chemically modified three-dimensional electrodes under typical conditions. Even for reactions with low exchange currents, considerable non-uniformity of activation is predicted in the direction of current flow so that the electrode cannot be scaled-up indefinitely in this direction without penalty. At the same time the conversion per pass of the electrode is so low that it can be considered to be a constant concentration system. An approximate economic forecast based on the results of the model suggests production costs of the order of $500 to $5000 kg−1 for a product of molecular weight 200, depending on the thickness of the electrode and the maximum permissible overvoltage. Installed capital costs are estimated to total about $ 100000 for a capacity of 20 to 170 kg−1 y−1) also depending on the maximum permissible overvoltage.
