The ZCF3 generated the highest performance of 2800 +/- 14.5 mWm(-2) (5.9 Am-2) compared to CEM: 1800 +/- 17.8 mWm(-2), 4.0 Am-2. Meanwhile, the CEM exhibited maximum power decline during the reverse sweep (61.7%) when analyzed using the bi-directional polarization method. The non-ion selective membranes displayed reduced in maximum power decline during the reverse sweep (ZCF1 50%, ZCF2 40% and ZCF3 42.8%). In addition, the ZCF3 showed the highest proton conductivity and water uptake, 0.863 x 10(-1) Scm(-1) and 93.7% respectively, followed by ZCF2 (0.729 x 10(-1) Scm(-1), 80.98%), ZCF1 (0.624 x 10(-1) Scm(-1), 73.99%) and Nafion 117 (0.367 x 10(-2) Scm(-1), 57.07%). The ZCF3 appeared as an efficient material for electrochemical active bacteria, maintaining the high power of 1600 mWm(-2), compared to CEM: 600 mWm(-2) after eight months' operation under batch mode. The long-term operation of MFCs was affected by the reduction of power output, caused by the increase in the thickness of the biofilm.
