Microbial Fuel Cell (MFC) technology provides the potential of utilising wastewater treatment plants as power generation units. The biogenic bacteria cultures used in this study were collected from marine environment in South Africa (Saldanha Bay, South Africa). The MFC was configured to operate without a cathode chamber using an air-cathode configuration. Biological deposition of Pd(0) nanoparticles was used to improve the electrocatalytic activity of the anode. Solid material such as a carbon rod has a low surface area compared to dispersed material such as granular activated carbon (GAC) when using the same amount of mass. Therefore, GAC is a viable replacement to solid material anode electrodes which is proposed to improve MFC performance since the anode surface area plays a crucial role in MFCs. The use of parallel configuration is proposed in this study since it leads to a high current and power density operation.
