Abstract

Two double chamber microbial fuel cells with different configurations were developed to produce electricity food waste leachate and studied for 30 days. Anode and Cathode were made by uncoated carbon felt and graphite rods.  Food waste and water were incubated into the reactor. After more than 30 days, leachate with the neutral condition (pH 6.9) was collected from the leachate reactor. 500 ml leachate was used in the anode chamber and 500 ml catholyte was used in the cathode chamber. The first configuration, non-aerated MFC, the maximum OCV, maximum power density, average power density, and maximum current density were 373 mV, 25.7 mW/m2, 3.7 mW/m2, and 21.4 mA/m2 respectively. For the second configuration, aerated MFC, maximum OCV, maximum power density, average power density, and current density were 404 mV, 25.7 mW/m2, 6.1 mW/m2, and 21.4 mA/m2 respectively. Aerated MFC had higher maximum OCV and average power density than non-aerated MFC. From the study, supplying continuous dissolved air (oxygen) in the cathode chamber can produce more voltage and average power density in double chamber microbial fuel cell.

Abstract

This study was aimed at evaluating the effect of sodium acetate on the performance of aerated double chamber microbial fuel cells from tofu whey. Six different mass of sodium acetate was soluted in the anode chamber (0, 1, 2, 3, 4, and 5 gr). The value of open circuit voltage (OCV) was taken to analyze the performance. A double chamber microbial fuel cell (MFC) was developed to produce electricity from tofu whey and studied for 1680 hours (70 days). Anode and cathode were made by uncoated graphite rod. After 1680 hours, the electricity production characteristics were obtained. The results show that the highest OCV (274 mV) was reached by adding 5 gr of sodium acetate in the anode chamber. Furthermore, adding 5 gr sodium acetate in the anode chamber could provide more stable OCV then other (0, 1, 2, 3, and 4 gr sodium acetate). From the study can be concluded that adding the sodium acetate in the anode chamber can provide stable and higher OCV.

Abstract

This study was aimed at evaluating the performance of double chamber microbial fuel cell from tofu whey. The value of open circuit voltage (OCV) and surrounding temperature were taken at four different time which were 6 am, 12 pm, 6 pm, and 12 am. A double chamber microbial fuel cells (MFC) with different was developed to produce electricity from tofu whey and studied for 7 days. Anode and cathode were made by uncoated graphite rod. After 7 days, the electricity production characteristics at four different time were obtained. The results show that the average maximum OCV was reached at 6 pm during the MFC operation. This study also indicated that higher surrounding temperature provide higher electricity production. The optimum surrounding temperature of this study was 31ËšC.
