A conducting polymer coated stainless-steel wool (SS-W) is proposed for use as a low-cost anode for microbial fuel cells (MFCs). When coated with polyaniline (PANi) and polypyrrole (PPy), the pristine SS-W, SS/PANi-W and SS/PPy-W anodes produced maximum current densities of 0.30 +/- 0.04, 0.67 +/- 0.05, 0.56 +/- 0.07 mA cm(-2), respectively, in air-cathode MFCs. Also, based on achieved power density, both SS/PANi-W and SS/PPy-W achieved 0.288 +/- 0.036 mW cm(-2) and 0.187 +/- 0.017 mW cm(-2), respectively, which were superior to 0.127 +/- 0.011 mW cm(-2) obtained with pristine SS-W. Further, in comparison with SS-P based anodes, all SS-W based anodes gave improved power densities under similar experimental conditions by at least 70%. Moreover, the charge transfer resistance of the SS-W was much lower (240 +/- 25 Omega cm(-2)) than for the SS-P (3192 +/- 239 Omega cm(-2)). The j(0(apparent)) values obtained for SS/PANi-W (0.098 +/- 0.007 Omega cm(-2)) and SS/PPy-W (0.036 +/- 0.004 mA cm(-2)) anodes were also much higher than that of the pristine SS-W (0.020 +/- 0.005 mA cm(-2)), as well as than those of all SS-P based anodes. The observed enhancement of the bioelectrocatalytic performances were well supported by physicochemical and electrochemical characterisation.
