Microbial fuel cells

  1. 1. Microbial Fuel Cells: Conversionof Organic Matter to ElectricityMiss Jiraphorn Lubsungnoen ID: M5430116School: BiotechnologyInstitute: Agricultural TechnologyThesis advisor: Asst. Prof. Dr. Apichat Boontawan
  2. 2. IntroductionMicrobial fuel cells (MFCs)
  3. 3. Objective• To demonstrate electricity could be generate from wastewater.• To examine efficiency of wastewater degradation when using MFCs.
  4. 4. Methodology MFCs configurations and running• Flat plate microbial fuel cell• Ethanol wastewater >> source inoculums and substrate• Phosphate buffer solution >> Basal medium
  5. 5. Analyze• Voltage output and power generation• Chemical oxygen demand (COD) removal of the wastewater
  6. 6. Result from previous research Substrate Source Type of MFCs Current density inoculums (mA/cm²)Corn stove Domestic Single chamber/ 0.15biomass wastewater carbon paper anode /carbon cloth cathodeEthanol Anaerobic Double chamber 0.025 sludge from aqueous cathode wastewater /carbon paper plant electrodesStarch Starch Single chamber 0.09processing processing /carbon paper anode /wastewater wastewater air cathode
  7. 7. Discussion• The factor that affect the MFCs performance are substrate , source inoculums, type of MFC ,operation condition and other.• Application of MFCs are limited because of their low power density .
  8. 8. Conclusion• Electricity will be generating from MFCs using ethanol wastewater as substrate. So , this study will be leading improve the performance of MFCs for practical application.
  9. 9. Thank you
