Abstract
A theoretical model is presented for a Teflon-bonded carbon porous diffusion electrode used for oxygen reduction in alkaline solution. The model is of the flooded agglomerate type and is extended to allow parameter estimation by regression analysis of polarization data. The data presented are for a Teflon-bonded carbon electrode (silver catalyst) tested in a laboratory scale cell using 3.5M (150 kg/m3) sodium hydroxide solution at 348 K with three different oxygen feed mole percents: 10, 20, and 100%. Regression indicates that the diffusion processes in both gas and liquid phases contribute significantly to polarization. © 1985, Taylor & Francis Group, LLC. All rights reserved.
