Reactions at gas-diffusion electrodes are modeled by treating the electrolyte meniscus geometry as a wedge. The resulting differential equations are solved analytically for the constant-overpotential case and numerically for all forms of polarization. The model's prediction agrees with experimental

All forms of polarization losses are considered. It is not possible to obtain analytical solutions for the apparent current-density/overpotential and current-distribution relations under these conditions. Analytical solutions are, however, possible for some special cases, viz activation-ohmic and c
