The effect of connection type in series and parallel on electric power generation of mud microbial fuel cell

Abstract

To investigate an effect of connection type in series and parallel on an electric power generation, a microbial fuel cell using a mud (MMFC) was constructed by 4 pieces of anode and one cathode with an external resistance. The maximum current observed at the parallel type MMFC was ca. two times larger than that at the series type MMFC, although the maximum voltage did not depend on the connection type. As a result, the parallel type MMFC showed ca. two times higher maximum electric power than the series type MMFC. Each anodic potential was depended on the connecting order, when the external resistance value used was close value to the internal resistance of the MMFC.
