Long-term test of the MFC. Anode chamber: S + AB7-f + B. subtilis bioanode and PWW as substrate (pH = 9.2). Cathode chamber: 20% Pt/C catalysts in KOH (pH = 9.7) electrolyte. Nafion® 117 alkalinized membrane was used as separator. (a) Ecell-j and Pcell-j curves obtained at the initial of the test, (b) Pcell-j curves obtained during the initial, days 1, 7, and 14, and (c) open circuit voltage of the MFC vs. time using a Rext = 10 kΩ.
