The diffusion coefficient, D, and the ionic mobility, \mu, in the protonic conductor ammonium ferrocyanide hydrate have been determined by the isothermal transient ionic current method. D is also determined from the time dependence of the build up of potential across the samples and theretical expressions describing this build up in terms of double exponential dependence on time are obtained. The values obtained are $D = 3.875×10^{-11}m^2s^{-1}$ and $\mu = 1.65×10^{-9} m^2V^{-1}s^{-1}$.
