ELectrochemical sensing problem

[vinke]

Anyone knows how to derive Fick's law of diffusion:

I=Jmf

Given current density applied to electrochemical sensing:
I= nAve

where :
I=current
J=flux
m=number of electrons
F=faraday constant
v=speed of particles
n=number of charge carriers/vol
A= cross-sectional area of sensor(electrode)
e=charge of an electron


Please help, at least give a clue where to start and the procedings.
Thanx
