Microbial fuel cells (MFCs) are electricity generating devices that use microorganisms as a biocatalyst. The chemical energy stored in organic materials is converted into electrical energy by microorganisms. During oxidation process, electrons are generated and collected by current collectors. The current collectors transfer the electrons to electrode which then flows to the external circuit. In this process, electricity is generated and can be used for useful work. But MFCs face challenging issues that have to be solved for critical application. Current collector is one of the key factors that affect the efficiency and cost of MFCs. In this study, the effect of contact area between anode and current collector using Titanium wire (Ti-wire) and Titanium mesh (Ti-mesh) and the effect of Titania (TiO2) 1D nanostructure were investigated. Glucose (1 g/L) is used as substrate and microorganisms were obtained from wastewater taken from Hyeonpung sewage treatment plant. The MFC with Ti-mesh based anode showed the highest maximum power density (16.3 W/m3).
