Microbial fuel cells (MFCs) generate electricity through bacteria that catalyze the oxidation of organic and inorganic matter. MFCs have three main components - an anode where bacteria adhere and produce electrons, a cathode where oxygen is reduced, and a membrane separating the two. As bacteria respire, they transfer electrons to the anode which flow through an external circuit to the cathode. MFCs can treat wastewater while generating electricity and have applications for powering remote devices, biosensing, and more. However, challenges remain in scaling up designs and reducing internal resistance for practical applications.

1. Let there be light!!

3. MICROBIAL FUEL CELL Waste water treament and electricity generation

9. 3 main components

10. How does it work?

13. A N O D E and c a t h o d e conductive Chemically stable biocompatible Non corrosive Stainless steel mesh Graphite plates Glassy carbons platinum

14. TYPES OF MFC 1. ANY MICROBE CAN PRODUCE ELECTRICITY WITH AN ELECTRON SHUTTLE (INEFFICIENT) 2.MEDIATORS ARE MOSTLY PHENOLICS WHICH ARE EXPENSIVE & TOXIC 1.NO ADDITIONAL ELECTRON SHUTTLE IS NEEDED 2.FEW KNOWN MICROBES HAVE THIS ABILITY 3.SHEWANELLA AND IRON REDUCERS DO!

22. Continuous mfc
