Abstract A one-dimensional numerical model to describe gas void fraction and current distribution in five model membrane cell configurations is described in this work. The five models describe ideal (equipotential), upright (top cathode/bottom anode), inverted, u- and n-type electrical connections with anodic chlorine and cathodic hydrogen evolution in each case. In all but the first case the finite resistances of the electrodes are taken into account. The effects of (a) different terminal arrangements, (b) different current densities, (c) different cell heights, (d) different compartment widths, and (e) different overvoltages, have been investigated. For each study the current distribution and anolyte and catholyte void fraction distribution is displayed. The resistive components of the cell voltages are also calculated; the calculated resistive voltage loss varies between extremes of 0.291 V for the ideal cell to 0.377 V for the inverted cell at 3 kA m−2 and 0.25 m cell height with typical fixed values of other parameters.
