Abstract
Moving towards green technology, alternatives to current detrimental, unsustainable, and expensive energy applications for eco-friendly energy are attracting great attention. Resource recycling and the convenient treatment of animal waste to diminish its nature impact are recently momentous subjects. Microbial fuel cells used cow waste have remarkable potential in electrical energy generation for clean, renewable and sustainable operation. In this study, double-chambered MFC was manufactured using cow manure as raw material at the anode chamber, graphite as the anode and cathode electrodes, fountain water in the cathode chamber, and proton exchange membrane. Because bacteria a catalytic reaction for the latent chemical energy of the cow manure was effectuated as a result of this, MFCs produced electricity. Electricity production performance of this MFC at low temperature (0–10 °C) conditions was examined. This MFC produced a maximum of 204.9 ± 0.1 mV open circuit voltage and 57.387 mW/m 2 power density under low temperature conditions. In particular, the sustainability and applicability of MFCs have been increased thanks to this operation done at low temperatures (0–10 °C).
