Abstract

Microbial fuel cells (MFCs) are a newly emerging technology in bioenergy processing. This research is to replace the use of platinum catalysts. Three types of oxygen reduction catalysts (B12/XC-72, B12/CNT and B12/AC) are analyzed and compared with the other two activated sludge and no catalyst where the performance of activated carbon in MFCs are evaluated. The results show that the catalyst with B12 vitamin as the main body has a higher open-circuit voltage. Among them, the open-circuit voltage of B12/CNT is the highest with 0.667 V, which is about 2 times that of MFCs without catalyst. The highest electrical performance with 0.54 W m−2 is 3.17 times that of catalyst-free MFCs, which shows that the self-made B12/CNT catalyst MFCs have the best performance in this study. The related research will be helpful for the application of wastewater to energy.
