MANUFACTURING METHOD OF CATHODE OF MICROBIAL FUEL CELL AND CATHODE OF MICROBIAL FUEL CELL MANUFACTURED BY THE SAME

摘要

The present invention relates to a cathode of a microbial fuel cell (MFC) and a method for manufacturing the same, wherein the method for manufacturing a cathode of an MFC comprises the steps of: mixing sodium dodecyl sulfate (SDS), multi walled carbon nanotube (MWCNT), FePC and CuPc with distilled water to prepare a mixed solution (Step 1); stirring the mixed solution (Step 2); performing microwave processing to the stirred mixed solution (Step 3); separating the mixed solution processed with microwaves by a centrifuge and then removing a supernatant to obtain a catalyst (Step 4); adding an ethanol to the catalyst to wash SDS (Step 5); separating the washed catalyst and the ethanol by a centrifuge and removing a supernatant to obtain the washed catalyst (Step 6); adding a nafion solution to the washed catalyst and stirring the mixture to prepare a catalyst for a cathode (Step 7); and screen printing the catalyst for a cathode on the surface of a cathode to prepare an MFC cathode (Step 8), wherein the maximum power density of an MFC using an MFC cathode including a Cu-Fe catalyst is very higher than the maximum power density of an MFC using an MFC cathode including a platinum catalyst. Therefore, the MFC cathode of the present invention is advantageously moderate in price and has excellent performance, compared with a conventional MFC cathode using a platinum catalyst.
