https://doi.org/10.1351/goldbook.D01726
Defined by the equation: δ=Dkd=n F D c Ali where D is the
diffusion coefficient
, kd is the
heterogeneous diffusion rate constant
, F is the
Faraday constant
, c is the concentration, A is the geometric area of the electrode, li is the
limiting current
and n is the
charge number of the cell reaction
.
