A PDMS Fabricated Miniature Microbial Fuel Cell

Abstract This study presents a new miniature - microbial fuel cell MFC platform which has been built by using polydimethylsiloxane PDMS. The MFC design includes PDMS soft chambers featuring carbon cloth electrode gold nanoparticles and a delivery system of electrolytes mcL. Bioelectricity was generated using Pseudomonas aeruginosa cultivated on simple nutrient medium. P.aeruginosa in the anode chamber forms biofilm and generates electrons which flow from anode to cathode through external load and generates current while protons pass through the salt bridge to cathode chamber. These mini-MFC exhibited fast start-ups reproducible voltage generation and enhanced power densities up to approximately 2.1mV.
