Abstract

The present study describes a simple, membrane-less, single-chamber microbial fuel cell (MFC) that uses natural mud and surface water as sustainable bioelectricity substrates. The way the system mimicked sediment-water interfaces was dependent on native microbial communities effecting electrochemical reactions without proprietary membranes. Carbon rod anodes were buried in anaerobic mud to establish a microbial colony while stainless-steel mesh cathodes were introduced in aerobic water for oxygen reduction. Both voltage output and other parameters like pH, temperature, turbidity, and conductivity have been measured during the experiment. Monitoring revealed rising voltage levels and biofilm formation around the anode, indicating active microbial processes and effective electron transfer. It thus provides an indication of the role of cheap, green ecofriendly MFCs in decentralized energy and wastewater treatment, particularly in situations where resource possibilities are limited.
