Series and hybrid connection of sediment microbial fuel cell for powering Led

Abstract

Sediment microbial fuel cell (SMFC) is a bio-electrochemical device which generates green electricity from microbes. SMFC are projected to be employed as a sustainable power source for led lighting and remote environmental observing. To understand the performance of SMFC, experiment performs for one month. Single SMFC has low voltage and current level which is unable to drive electronic devices. To increase power generation from SMFC, eight individual SMFC are connected together either in series or in hybrid connection. Two combinations of this SMFC, hybrid connection, are proving to be the more effective one, step-up both the voltage and current level, mutually. Polarization curve and behavior of voltage generation experiments are done for series and hybrid connected SMFC. The power density is obtained 1.111mW/m2 at $435.25 \boldsymbol{\mu} \mathbf{A}$ from series and 1.309mW/m2 at $870.75\boldsymbol{\mu} \mathbf{A}$ in hybrid connected SMFC. This study suggests that maximized the power production of SMFC by connecting series and hybrid for practical use of the device.
