Research on the Performance of Bio-electro-Fenton Microbial Fuel Cell of 316SS Electrodes Using Atmospheric Plasma Treatment

生物-電-芬頓燃料電池（Bio-electro-Fenton Microbial Fuel Cell, MFC）是兼具發電與汙水處理的新能源技術，系統利用氧化還原原理，陽極以微生物菌種分解有機物產生電能，陰極以芬頓原理進行汙廢水處理，兼具改善環境並獲取能源功能，漸為世界各國深入研究。本研究利用316SS不銹鋼進行常壓電漿表面處理後替換傳統之碳氈電極，進行生物-電-芬頓燃料電池性能及抗腐蝕性效應探討。結果顯示，在系統電性表現上，由極化曲線量測結果，316SS電極處理後電流密度提升2.2倍，功率密度提升2.7倍；在腐蝕電位量測部分，未進行電漿處理之316SS電極腐蝕電位為-194mV vs Cl/Hg2Cl2，處理後之電極腐蝕電位可達到135mV vs Cl/Hg2Cl2。

Bio-electro-Fenton Microbial Fuel Cell (MFC) provides both electricity and sewage treatment for new energy technology, the system architecture is the oxidation and reduction reactions. Microorganisms were decomposed organic substances to produce electricity at anode, while the Fenton sewage wastewater treatment was performed at cathode. The system combines features of energy and the environment improvements, which draws more attention of all countries in the world. In this study, the traditional carbon felt electrodes was replaced by 316SS stainless steel after atmospheric plasma surface treatment and their battery performance and corrosion resistance were discussed. The results show that the electrical performance of the system by polarization curve test, a current density of 316SS after electrode treatment improved 2.2 times, while its power density was raised 2.7 times. The corrosion potential of 316SS electrode without the plasma processing is -194mV vs Cl / Hg2Cl2, and the one with the plasma processing is 135mV vs Cl / Hg2Cl2.
