FUEL 133 |
| A microbial fuel cell converts chemical energy, available in a bio-convertible substrate, directly into electricity. It works through the action of bacteria, which can pass electrons to an anode of a fuel cell. The electrons flow from the anode through a wire to the cathode, producing an electric current. In the process, the bacteria consume organic matter in the surrounding liquid medium. The limiting step for the entire process is the electron transfer from bacteria surface to the electrode material. Introduction of carbon nanotubes into microbial culture creates a 3-D conductive network that allows avoiding transport limitations. Presented experimental data with corresponding theoretical model indicate significant increase of energy yield. |
