Abstract

Developing an appropriate diffusion mechanism to analyze the gas transport in porous electrodes of SOFCs (solid oxide fuel cells), has been a crucial step towards analyzing accurately the cell performance. In this report, the errors in evaluating the gas diffusivity, limiting current density and concentration polarization, are calculated quantitatively by taking bulk diffusion and the previously-overlooked Knudsen diffusion into account. In particular, this work analyzes the deviation between ignoring and considering the Knudsen diffusion of hydrogen transport in SOFC anodes. The study facilitates the rational pre-evaluation of micro- and nanoscale materials prior to assembly into SOFCs.
