Abstract
⺠Power density curves often show power overshoot, where the current decreases as the voltage is reduced. ⺠Microbial fuel cells (MFCs) showed power overshoot when acclimated to higher resistances but not lower resistances. ⺠Power overshoot was eliminated by acclimating all reactors to a low external resistance of 5 Ω. ⺠MFCs that did not show power overshoot had redox activities over a broader range of anode potentials in first derivative cyclic voltammetry plots. ⺠These results show that power overshoot can be eliminated in MFCs, making it possible to more accurately estimate power production by the MFC.
