sMFC

Caption

sMFC components and experimental installation plan depict two sMFCs with identical sediment-buried graphite anodes wired (in red) to transmit microbially-generated electric current from anodes to an upper cellular data relay unit (upper box) that transmits the data from the field site. Electrons then pass via wires (green) to carbon cloth cathodes (grey ovals) suspended in the water at variable depths. Leftmost sMFC features a surface cathode while the sMFC at right has a submerged cathode. Identical replicate sMFCs (not shown) were included in the study.
