A benthic microbial fuel cell (BMFC) is an eco-friendly energy conversion device that uses electricity generated by benthic microorganisms decomposing organic matter in the mud of the sea or lake. In this study, in order to understand how domestic wastewater flowing into tidal flats affects the performance of BMFC. BMFC performance was compared and reviewed by fermenting organic substances in food and mixing them with tidal flats. Performance of the BMFC was improved by 49% by adding fermented food rich in vitamins (B₂, B₆, B₁₂, C, D, E) and soft flour. The maximum power density increased as the amount of fermented organic matter increased, and it was shown that the fermented organic matter fermented during 25~29 days was optimal for BMFC.

A benthic microbial fuel cells(BMFC) is fuel cell using electricity produced by decomposing organic matter in a sea or a lake. In this study, we used a gas diffusion layer (GDL) of a polymer electrolyte fuel cell (PEMFC) as a BMFC electrode to find out the operation conditions with high performance. The performance of BMFC was increased as resistance of external resistor increased. It was possible to maintain the performance by avoiding the increase of the contact resistance with the electrode due to corrosion of the lead wire in seawater. The bubble generator was able to increase the maximum power density by more than 2 times and the optimum operating temperature was $40^{\circ}C$.
