An analytical expression of the current generated from the electrochemical reaction in a porous r... more An analytical expression of the current generated from the electrochemical reaction in a porous rotating disk electrode (PRDE) is derived when the reactant transport is dominated by advection and diffusion. Simple algebraic expressions for the concentration of reactant and the current response are obtained as a function of the rotation rate, reaction rate, permeability of the porous medium, diffusion coefficients, kinematic viscosity, and geometry of the porous film. Upon comparison, the analytical expression of current in this work coincides with the existing results for the limiting case of low rotation rates. Also the concentration/current expressions here derived are in satisfactory agreement with numerical results.
