Microbial Fuel Cells (MFC) are robust devices capable of taping biological energy, converting sugars into potential sources of energy. Persistent efforts are directed towards increasing power output. However, they have not been researched to the extent of making them competitive with chemical fuel cells. The power generated in a dual-chamber MFC using neutral red (NR) as the electron mediator has been previously shown to be 152.4 mW/m2 at 412.5 mA/m2 of current density. In the present work we show that Pt thin film coated carbon paper as electrodes increase the performance of a microbial fuel cell compared to conventionally employed electrodes. The results obtained using E. coli based microbial fuel cell with methylene blue and neutral red as the electron mediator, potassium ferricyanide in the cathode compartment were systematically studied and the results obtained with Pt thin film coated over carbon paper as electrodes were compared with that of graphite electrodes. Platinum coated carbon electrodes were found to be better over the previously used for microbial fuel cells and at the same time are cheaper than the preferred pure platinum electrodes.

The electrode material has the very important influence to the microbial fuel cell. The different electrode materials were studied for producing the electricity performance to MFC by the activated sludge as the substrate. The results indicated that the anode of graphite pole was 0.63 mW/cm2 of the area power density. The carbon paper was 60 (0.50mW/cm2). Carbon paper 90 was 0.23mW/cm2. Although having the biggest area power density, the general trend of the graphite pole is much lower than others and production of the electricity was not good. Even though the maximum of area power density of graphite pole, it might be the reason for increasing nutritive compound and elevation of temperature. The carbon paper 90 produce the area power density is the steadiest among three poles and its output voltage is a quite stable and low. MFC is excellent under carbon paper 90. The area power density had strong fluctuating scope, the power density is big and the overall value is high under carbon paper 60.

Nanocomposite Catalysts

Metal, as a high-performance electrode catalyst, is a research hotspot in the construction of a high-performance microbial fuel cell (MFC). However, metal catalyst nanoparticles and their dispersed carriers are prone to aggregation, producing catalytic electrodes with inferior qualities. In this study, Pd is uniformly dispersed on the graphene framework supported by carbon black to form nanocomposite catalysts (Pd/GO-C catalysts). The effect of the palladium loading amount in the catalyst on the catalytic performance of the air cathode was further studied. The optimized metal loading afforded a reduced resistance and improved accessibility of Pd particles for the ORR. The maximum current output of the 0.250 Pd (mg/cm2) MFC was 1645 mA/m2, which is 4.2-fold higher than that of the carbon paper cathode. Overall, our findings provide a novel protocol for the preparation of high-efficient ORR catalyst for MFCs.
