The Effect of Multiple Electrode Pairs to Electricity Potential of Ceramic-Based and Tempe Waste Microbial Fuel Cell

Abstract

Ceramic is low-cost separator membrane has widely applied in dual-chambered Microbial Fuel Cell (MFC). Its big pores and other chemical and physical advantages make it suitable to substitute expensive exchange separator membranes. The purpose of this study is to enhance electricity of ceramic-based microbial fuel cell by using various number of carbon electrode pairs. This study uses tempe waste as anolyte and KMnO4 as its catholyte to gain electricity. Three variety of electrode pairs data of electricity result is processed statistically to examine significant difference of voltage, current, and power density as parameters. The result of this study shows that electricity of three-electrode pairs has a higher average of power density with the number 1447,91 mW/m2, the difference between three and two electrode pairs is around 588 mW/m2 and between three and one electrode pairs is 910 mW/m2. It has significant difference between one, two, and three-electrode pairs in the parameters.
