Abstract

This article focuses on the development and evaluation of low-cost anode materials for soil microbial fuel cells (SMFCs) using rice husk charcoal (RHC) and Bokuju, a Japanese black drawing ink. The study found that incorporating RHC with Bokuju significantly improved SMFC performance, increasing maximum power density by 134% to 9.52 μW/cm² and reducing start-up time compared to using Bokuju alone. The ratio of RHC to Bokuju influenced the power output, with an optimal composition identified at 20% RHC, and UV ozone treatment of the anode surface further enhanced performance by removing impurities. These findings suggest that waste rice husks combined with Bokuju offer a promising, cost-effective anode material for SMFCs, with potential for further optimization.
