Abstract
A model is developed for analysis of porous gas electrodes in which an electrolyte film exists on the walls for part of the gas filled section of the pore. The influence of electrode kinetics and transport of current in the film is considered along with that of dissolved gas diffusion. It is found that the reaction occurs over lengths of film from the intrinsic meniscus equal to thousands of film thicknesses and that diffusion of dissolved gas is not controlling under most circumstances. An example based on the oxygen electrode in KOH solution is treated.
