Electrochemical characterisation of the mature SSM-MFCs. a) Voltage-current polarisation curves of the whole cell form OCV to 50 mV. b) Potential-current polarisation curves of the cathodes. c) Potential-current polarisation curves of the anodes. The curves are the average of each conditions duplicates and the error bars stand for the values range. N.B. The cathode potential-current curve for the fully submerged44condition, is shown in the anode graph, due to its negative values.
