= Limiting current density
{title2=$j_L$}

A limiting rate of charge transfer per area imposed by reactant transport or another bottleneck. In a simple <diffusion> film, $j_L=nFDc_b/\delta$ and a consuming <electrode> has $c_s/c_b=1-j/j_L$. Increasing internal roughness does not necessarily increase external mass-transfer flux proportionately.
