  • Diffusion current is governed by Fick’s Laws of diffusion. It is the principle on which many electroana- lytical methods are based, because the current is proportional to the bulk concentration of the diffusing species. I_{d} = z*F*A*D*\grad(c)_{x=0}, where z is the electron number of an electrochemical reaction, F the Faraday constant, A the electrode surface area, D the diffusion coefficient of electroactive substance, and (∂c/∂x)x=0 the gradient of the amount concentration at the electrode surface position x = 0.
