The aim of this work was to establish a mathematical model based on Tafel equation to quantitatively relate the maximum volumetric power (PV,max) as well as the internal resistance (Rint) in a microbial fuel cell (MFC) with the specific surface area of the graphite anodes ðA0 s Þ, and either their conductance C or electrolytic conductivity s of the material. The anodic chambers of the cells were packed with different anodic materials (graphite rods (GR), triangles of graphite (GT) and graphite flakes (GF), in order of increasing A0s). The Rint decreased and the PV,max increased for cells equipped with GR, GT and GF anodes. There was a correspondence of either the decrease of Rint or the increase of PV,max with the increase of the log of A0s of the graphite anodic materials.
