An one-dimensional mathematical model for fluidized-bed electrode
is presented Exact solution in closed from for over potential distribution are obtained for a single oxidation-reduction reaction under activated control with charge transfer coefficients of 1/3
1/2
2/3 respectively. Polarization equations for reactions under activated control
diffusion control
mixed control and/or with side reactions occurring are derived for random charge transfer coefficients accompanied by rather high dimen-sionless resistance parameter. Results thus obtained may be used for the description of behaviours in flooded porous electrodes and tubular electrodes. Parametric effects on current efficiency was discussed.
