Answer: C
Microbial fuel cell (MFC) is a type of bioelectrochemical fuel cell system that generates electric current by diverting electrons produced from the microbial oxidation of reduced compounds (also known as fuel or electron donor) on the anode to high-energy oxidised compounds such as oxygen (also known as oxidising agent or electron acceptor) on the cathode through an external electrical circuit.
It is a bio-electrochemical system that uses bacteria as the catalyst to oxidise organic and inorganic matter, and consequently, generate electric current out of it.
