摘要
The bipolar electrochemistry in a U-type cell equipped with a shielding wall was investigated in detail using a number of electrochemical measurements for the bipolar electrode (BPE). Measurement of the IR-drop in a U-type cell and the potential on the BPE afforded similar sigmoidal potential distribution profiles at around the shielding wall. The current through the BPE was also measured using a split BPE with and without a conducting polymer on its surface. The conducting polymer film lowered the potential threshold for electrochemical reaction at the anode, but prevented cathodic reactions such as the reduction of contaminant oxygen. These results strongly support our preliminary work on the electrochemical modification of conducting polymers using bipolar electrochemistry.
