Electricity Generation of Plant Microbial Fuel Cell (PMFC) using Cyperus Involucratus R.

Abstract

This research is a study of microbial fuel cells produce electricity from plants using Cyperus involucratusR. called Plant Microbial Fuel Cell (PMFC). As a result of the polarization curve, by adjusting the external resistance between 10 to 12,000 ohms, it was found that the internal resistance of PMFC1, PMFC2, MFC1 and MFC2 was 9.78, 11.06, 9.47 and 11.92 ohms respectively. The results showed that the optimum size of the anode electrode is 242 square centimeters and adding soil by using the external resistance 100 ohms. The highest average power density equaled to 5.99 milliwatts per square meter of the anode electrode. Finally the wastewater in PMFC was reduced 53.5 percent in the period of 5 days compared with un-treated wastewater.
