A Review On Electrode Materials in Microbial Fuel Cell Fabrication

Abstract

Electrical energy needs in Nigeria are expected to continue to rise due to the rise in population. The use of petroleum as a source of energy still dominates till date, although oil reserves in Nigeria are increasingly being depleted. There is therefore the need to develop alternative source of sustainable energy, such as, Microbial Fuel Cell (MFC). Electrode materials are critical for microbial fuel cells (MFC) due to their influence in the construction as well as operational costs. In this study, we reviewed different kinds of electrodes used for the purpose of fabrication of MFC across the globe. The study shows that, most of electrode materials are carbon based perhaps due to their high conductivity, durability, eco-friendliness. While the likes Activated carbon and Biochar are selected for their surface area advantages, Graphenes, Carbon Nanotubes and Some Metals excel in the area of delivering high power density
