چکیده انگلیسی
Performance of microbial fuel cells (MFCs) with carbon supported nickel phthalocyanine (NiPc)MnOx composite (MFC-1) and nickel phthalocyanine (MFC-2) incorporated cathode was compared with a control MFC with non-catalysed carbon felt as cathode (MFC-3) and MFC-4 having Pt on cathode (as benchmark reference control). MFC-1 exhibited power density of 8.02Â Wmâ3, which was four folds higher than control MFC-3 (2.08Â Wmâ3) and 1.14 times higher than MFC-2 (6.97Â Wmâ3). Coulombic efficiency of 30.3% obtained in MFC-1 was almost double of that obtained for control MFC-3 and it was 5.4% lesser as compared to MFC-4 (35.7%). Linear sweep voltammetry study of cathodes revealed that NiPc-MnOx could enhance the electrocatalytic activity of oxygen reduction reaction (ORR) in comparison to control cathode. However, the power recovery from MFC-1 was noted little lower than what obtained from MFC-4 (10.58Â Wmâ3), however the cost normalized power was two times higher than Pt catalyst on cathode. Thus, NiPc-MnOx based catalyst developed in this study has potential to enhance ORR in cathodes of MFCs in order to harvest more power.
