a r t i c l e i n f o High-performance microbial fuel cell (MFC) air cathodes were constructed using a combination of inexpensive materials for the oxygen reduction cathode catalyst and the electrode separator. A poly(vinyl alcohol) (PVA)-based electrode separator enabled high coulombic efficiencies (CEs) in MFCs with activated carbon (AC) cathodes without significantly decreasing power output....

The application of a rotating cathode in a river sediment microbial fuel cell increased the oxygen availability to the cathode, and therefore improved the cathode reaction rate, resulting in a higher power production (49 mW/m(2)) compared to a nonrotating cathode system (29 mW/m(2)). The increased dissolved oxygen in the water of our lab-scale sediment MFC, however, resulted in a less negative ...

Metal, as a high-performance electrode catalyst, is research hotspot in the construction of 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 uniformly on graphene framework supported by carbon black form nanocomposite catalysts (Pd/GO-C catalysts). The...

A microbial fuel cell (MFC) has been developed for removal of sulfur-based pollutants and can be used for simultaneous wastewater treatment and electricity generation. This fuel cell uses an activated carbon cloth+carbon fibre veil composite anode, air-breathing dual cathodes and the sulfate-reducing species Desulfovibrio desulfuricans. 1.16gdm(-3) sulfite and 0.97gdm(-3) thiosulfate were remov...

The increasing awareness that there are limits to the availability of nonrenewable resources, as well as that there are limits to the biosphere’s ability to absorb wastes, are at the basis of the growing interest about Microbial Fuel Cells (MFCs) technology, with particular regards to their application to wastes treatment. MFCs, in fact, couple the direct electric power production to the degrad...

An innovated wastewater resourcing system (WRS) was formal proposed to couple the production of polyhydroxyalkanoates (PHAs) and electricity generation by microbial fuel cell (MFC) with the proper controlled acidification digester. This paper gave the carbon audit and cost analysis of WRS to estimate its carbon emission, energy saving and profit production. Results showed WRS extracts 18% of in...

The first self-sufficient system, powered by a wearable energy generator based on microbial fuel cell (MFC) technology is introduced. MFCs made from compliant material were developed in the frame of a pair of socks, which was fed by urine via a manual gaiting pump. The simple and single loop cardiovascular fish circulatory system was used as the inspiration for the design of the manual pump. A ...

The practical implementation of air-breathing microbial fuel cell (MFC) is critically linked to the development efficient materials as cathode and electrochemically active biofilm-based anode. In this contribution, we demonstrate feasibility by decorating a 3D carbon felt electrode with Pt nanoarrays (CF@Pt) bifunctional material garden compost bioanode cathode. Half-cell electrochemical charac...

The microbial electrochemical cell (MEC) is a promising waste treatment technology to accomplish simultaneous alternative energy production and degradation of organic matters. Potato pulp waste (PPW) from a potato processing plant contains a large amount of carbohydrates that need be degradated before discharge into the environment. Here, we describe electricity generation in singlechamber micr...
