Membraneless 3D printed Fiber-Based Microbial Fuel Cells harnessing Pseudomonas Aeuroginosa for Energy Production

Fiber-based Microbial Fuel Cells (MFCs) are emerging as promising technology in the field of fuel cells. Due, to the features like its inexpensive nature, naivety in fabrication, and its abundance of availability they manifest an upper edge over the other fluidic-based MFCs. Fiber-based MFCs are the epitome of an electrochemical system that uses bacteria for power generation and wastewater treatment in the paper substrate. Fiber-based miniaturized devices have gained significant attention over the last few years due to their flexible application in medical science, biosensors, etc. This work fabricated paper-based miniaturized MFCs using a 3D printer. Carbon Cloth was used as the working electrode and Pseudomonas Aeruginosa (Pseudomonas A) as the fuel to generate power. A comparative study showed that the fiber treated in oxygen plasma showed an optimized power output of around 345.40 µW/cm

and a current output of 20.95 µA/cm
