The energy contained in wastewaters has been identified as a promising sustainableenergy resource that could be harvested by using microbial fuel cells (MFC). When dealing with realwastewaters, the MFCs should be able to manage high flow rates and flow rates fluctuations. In thiswork, the short-term effects of the influent flow rate variations on the performance of a microbialfuel cell has been studied. With this aim, the influent flow rate was stepwise increased from 0.72 to7.2 L/d and then stepwise decreased. The obtained results indicate that, on the one hand, an increasein the influent flow rate leads to higher chemical oxygen demand removal rates up to 396 g/(L/d) andhigher electric power generation almost 18 mW/m2, but to lower coulombic efficiencies. On the otherhand, the reduction of the flow rate increases the coulombic efficiencies, as well as the percentageof chemical oxygen demand removed, but decreases electric power generation. In the short-term,the exposition to higher influent flow rates causes the growth of the microbial population of the MFC,the growth of the non-electrogenic microorganisms being higher than that of the electrogenic ones.The higher growth of non-electrogenic microorganisms may lead to lower coulombic efficiencies.
