Two-component mass transport in the anode of solid-oxide fuel cells

On governing equations and closure relations for the multiscale modeling of concentration polarization in solid-oxide fuel cells: mass transfer and concentration-induced voltage losses.

“…In order to study the effect of pressure gradient on mass transfer in an SOFC anode, Grigoruk and Kasilova [ 274] have developed a simplified, one-dimensional mass transport model based on DGM, for which an analytic solution is obtained in the case wherein the fuel is not diluted by an inert component (they consider a two-component gas mixture). In essence, this model is akin to that of Virkar and coworkers, with the exception that in Eq.…”
