Driving force behind electrochemical performance of microbial fuel cells fed with different substrates.

The performance of miniaturized microbial fuel cells operating with five different substrates (acetate, lactate, glucose and octanoate) were studied with the aim to identify the reason for its different performance. In all cases, the COD removal rate was about 650 mg COD L-1 d-1. However, the bio-electrochemical performance of the MFC was very different… (More)
