Effect of configuration(structure of electrode,interelectrode gap,positions of inlet and outlet,volume of the cell and additional nets)on mass transfer characteristic of a filter-press type electrochemical cell has been studied.The mass transfer coefficients on the electrodes were obtained by using the well-known technique based on the determination of limiting diffusion current.It is found that mass transfer coefficients with mesh electrode are greater than that of with plate electrode.Mass transfer coefficient is decreased with interelectrode gap.While inte- relectrode gap achieved a certain value(7 mm),mass transfer coefficient is steady,no more declining.Mass transfer characteristic for different positions of inlet and outlet are different and dimensionless number groups correlated equations are obtained by experiment.Mass transfer characteristic is the best when inlet located on the top and out- let on the bottom of the cell respectively.While magnified the volume of the cell to eight times,mass transfer char- acteristic changes little.Mass transfer characteristic without nets is lower than that of with additional nets in the exit region,but higher than that of with additional nets in the entry region.

It is found that mass transfer coefficients with mesh electrodes are greater than that of with plate electrode. Mass transfer coefficient is decreased with interelectrode gap. White intelectrode gap achieved a certain value (7 mm), mass transfer coefficient is steady, no more declining. Mass transfer characteristic for different positions of inlet and outlet are different and dimensionless number groups related equations are obtained by experiment. Mass transfer characteristic is the best when inlet located on the top and out-let on the bottom of the cell respectively. Wide magnified the volume of the cell to e ight times, mass transfer char- acteristic changes little. Mass transfer characteristic without nets is lower than that of with with nets in the exit region, but higher than that of with with nets in the entry region.
