diffusion layer thickness

Defined by the equation:
δ = D k d = n F D c A l i
where D is the diffusion coefficient, k d is the heterogeneous diffusion rate constant, F is the Faraday constant, c is the concentration, A is the geometric area of the electrode, l i is the limiting current and n is the charge number of the cell reaction.
