Characterization of Capacitive Materials for their Application in Bio-Anodes

Biorecovery_v2.png

The depletion of fossil fuels, the increased environmental concerns and the rising of world energy consumption has led to the need of alternative energy sources that are clean and renewable. Microbial Fuel Cell (MFC) is a CO2 neutral, sustainable and efficient technology to recover electricity from organics in wastewater. Classical MFCs have limitations like energy losses in the anode/cathode or high material costs that can be overcome with capacitive MFCs, which use capacitive materials like activated carbon granules where the biofilm can attach.
