文摘
A 3-D macroporous anode composed of graphite rod arrays was developed. Current promotion was limited after the electrode array reached a high number. A significantly uneven current distribution was found in the macroporous anode. Proton transfer influenced the pH and biofilm distribution in the macroporous anode. The closer the segment was to the center, the lower the contribution to the total current.
