Embodiment

[0056] The following examples are included for illustrative purposes only and are not intended to limit the scope of the invention. All parts and percentages are by weight unless otherwise indicated.

[0057] Assembling a microbial fuel cell

[0058] A chamber 1.5 cm wide, about 4 cm long and 0.45 cm deep was machined in a 3 cm x 6 cm x 0.9 cm block of transparent synthetic resin (Lucite). Ports were drilled into the block to serve as inlet and outlet ports for solution flow. Two small holes for wire leads are drilled in the bottom of the chamber. One longer wire, Au, is used as a current collector and the other shorter wire, Pt, is used as an unloaded voltage probe. The leads are sealed in place with epoxy. A piece of carbon felt 1.52cmx3.0cmx0.45cm was placed in the chamber. The anion exchange membrane, a membrane made of polyolefin binder and ground anion exchange resin, was placed on the felt, and then a cathode consisting of Pt / C on a carbon paper support was cut to ...
