Multicomponent Gas Diffusion in Porous Electrodes [PDF]

open access: yesJournal of The Electrochemical Society, 2015
Multicomponent gas transport is investigated with unprecedented precision by AC impedance analysis of porous YSZ anodesupported solid oxide fuel cells. A fuel gas mixture of H2-H2O-N2 is fed to the anode, and impedance data are measured across the range of hydrogen partial pressure (10–100%) for open circuit conditions at three temperatures (800◦C, 850◦
