In this thesis we have demonstrated the use of high-performance electrodes are the prime step in the development of MFCs. The thesis describes the synthesis of polyaniline and polypyrrole on stainless steel wool electrode, and their use to evaluate the performance of the MFCs. In comparison with SS plate-based anodes, all SS Wool based anodes gave improved power densities under similar experimental conditions by at least 70%. Also, the synthesis and use of PANi-Cu composite for the development of a cheap and efficient cathode for MFCs. The j0apparent of the PANi(25 min) cathode was 170% higher than with 0.5 mg cm-2 Pt loaded cathode. Thus, demonstrating that the CP/PANi-Cu cathode was superior to the CP/Pt cathode. Finally, the fabrication of an 18 cell MFC stack containing PANi coated SS Wool is undertaken and then explored as an anode for power generation with landfill leachate. In the current generation mode, the develop electrodes may subsequently enable the deployment of the MFC stack in real wastewater process train as a pilot plant for power generation.
