Mass Transfer in Porous Gas Diffusion Electrodes. 2. Mass Transfer Through a Single Cylindrical Pore to a Semi-Infinite Reactive Cylinder

Abstract

The value for the maximum current density pre dicted by this model is approximately three times greater than the value obtained by Ariet and Distefano under the assumption of no elec trolyte penetration in the pore (semi- infinite annulus). One of the major assumptions of this model is that the liquid penetrates the pore to such an extent that the pore can be considered a semi-infinite cylinder. It was concluded from experimental data that any penetration depth greater than one pore diameter is sufficient to constitute a semi-infinite cylinder.
