A stacking microbial fuel cell in series with serpentine flow field(MFCS-S)was constructed by using four started-up single microbial fuel cells.The performance of the MFCS-S was tested and several possible measures of improving MFCS-S performance were investigated.The experimental results showed that a maximal power density of 2226 mW·m-2 was observed at a high voltage of 2.11 V.A cell with low performance in MFCS-S would present a reversed voltage at a certain current density and then result in a low stack cell
which was the main limitation of further improving MFCS-S performance.Although large improvement is impossible for the voltage reverse
an increase in the flow rate of the anolyte and catholyte in MFC-R can result in a significant improvement for power output of MFCS-S.By using a hybrid connection
the voltage reverse would be avoided
resulting in a largely increased stack performance. However
the voltage reverse cannot be improved by removing the MFC-R and even got worse after switching it into reverse in the series circuit.
