摘要

Optimizing electrode efficiency and durability is essential for the progression of microbial fuel cell (MFC) technology. This study investigates the performance enhancement of a single-chamber soil-compost microbial fuel cell (MFC) using SnO₂ and SnO₂/PPy-coated copper electrodes. Electrodes were fabricated via electrodeposition using chronoamperometry, and their electrochemical properties were analyzed through cyclic voltammetry (CV), linear sweep voltammetry (LSV), electrochemical impedance spectroscopy (EIS), and linear polarization resistance (LPR). The deposition of SnO₂ and SnO₂-PPy shifted oxidation peaks from 0.295 V to 0.531 V and 0.512 V, respectively, with improved redox peak currents. Power density measurements revealed significant increases, reaching 5.4 mW/m² and 10 mW/m² with current densities of 152.68 mA/m² and 187.65 mA/m² for SnO₂ and SnO₂-PPy coatings—approximately 11-fold and 21-fold higher than uncoated electrodes in the MFC system. Corrosion resistance improved substantially, reducing corrosion rates by a factor of six. Structural and surface morphology analyses were conducted using energy dispersive X-ray spectroscopy with scanning electron microscope (EDXS-SEM) and X-ray diffraction (XRD), confirming successful deposition.
