Sediment as New Source of Clean Energy for Bioelectricity Production

Sediment microbial fuel cells (SMFCs) are new technology for production of clean energy. SMFCs able to convert a wide range of organic matter contained in the sediment to bioelectricity. In this study four different ecosystems (sea، hatchery، river and spring) was evaluated to assess their potential to generate electricity. Graphites were used as anode and cathode electrode. The lowest produced voltage was around 310 mV and produced from hatchery. Compare to other ecosystems river generate highest maximum generated power density of 37. 09 mw/m2. The maximum generated voltage was 740 mV and it was completely stable for 12 days.
