Performance of the duplicate SSM-MFCs having submerged cathodes (green and blue). a) Temporal evolution of the power produced by both duplicate over a 30 days' period. Electrochemical characterisation of the cells after these 30 days with the current-power polarisation curves of the whole cell (b) and the current-potential polarisation of each electrodes (c). The orange curves are the average performance of the same duplicate prior the 30 days run and are extracted from Fig. 4, Fig. 5 ( condition). The arrow show the change of trend after 30 days of maturation. (For interpretation of the references to color in this figure legend, the reader is referred to the Web version of this article.)
