Abstract

Microbial fuel cells (MFCs) harness electrons from microbial degradation of substrates to produce electricity. Using more conductive and biocompatible materials and developing a higher density biofilm on the anode are two strategies for increasing power produced by MFCs. Latex polymers were combined with conductive materials, including carbon black and carbon nanotubes, to create a composite that is flexible, sturdy, and electrically conductive. These enhanced polymers can retain conductivity even with very small quantities of carbon nanotubes, reducing cost compared to the pure carbon-based material. Microbes were also enmeshed in latex polymers with CNTs at very high cell densities. The latex preparation allows diffusions of substrate to the entrapped microbes. A combination of latex with exoelectrogenic microbes and conductive materials will help increase anode performance and therefore the overall power generation of MFCs.
