Electrochemical Analysis of Shewanella sp. Behavior In Microbial Fuel Cells

A cube two-chamber microbial fuel cell cultivated with Shewanella sp. was investigated and analyzed in terms of voltage and current generation behavior, maximum attainable power, electrochemical activity, and operational considerations from the beginning. The results indicated that with a certain architecture of the MFC utilized in this study, 80% of the maximum power is achievable when the MFC reached a stable pattern of substrate consumption. 84.6 mW/m2 ofpower density was obtained at the resistance of 229 Ω. The configuration of the MFC allowed one of the lowest internal resistances to the time as 141 Ω.
