Abstract：The photosynthesis microbial fuel cell was constructed using separated Chlorella vulgaris. Electricity production and mechanism of the cell were preliminarily studied. By analyzing the cell voltage measured by the acquisition system, it was proved that the photosynthetic microbial fuel cell was feasible. Microbial electricity generation was mainly attributed to the electrochemically and biologically active cells attached to the electrode, and the suspended algae in the solution were not involved. The illumination was one of main influential factors on the voltage of MFC. By adding Fe3+ to the cathode chamber, electron transfer driving force was generated in coupling of Fe3+ reduction to Fe2+ on the cathode. The Fe2+ cations were subsequently oxidized by O2 in air. For this Fe3+ circular effect，the electron transfer and oxidation-reduction efficiency were enhanced. The output power density of MFC was up to 11.82 mV/m2, and the removal rate of COD reached 40%. This kind of MFC could produce electricity and treat the wastewater simultaneously.
