Numerical analysis on the anode active thickness using quasi-three-dimensional solid oxide fuel cell model

A quasi-three-dimensional solid oxide fuel cell (SOFC) model reduces the computational cost by strategically ignoring the thinnest direction in an SOFC by incorporating a chargetransfer current density model to represent its active thickness in electrodes to represent its complex phenomenon in an el...
