Fig. 3From: Enhanced electrical power generation using flame-oxidized stainless steel anode in microbial fuel cells and the anodic community structureComparison of FO-SSA with CCA and untreated SSA in MFCs equipped with membranes. The peptone medium was used as the feedstock for the MFCs. Power density (a), polarization curves for the anodes and cathodes (b), and CV profiles (c) are shown. In b, data for the anodes and corresponding cathodes are represented as solid and clear circles, respectivelyBack to article page
