In the past 10–15 years, the microbial fuel cell (MFC) technology has captured the attention of the scientific community for the possibility of transforming organic waste directly into electricity through microbially catalyzed anodic, and microbial/enzymatic/abiotic cathodic electrochemical reactions. In this review, several aspects of the technology are considered. Firstly, a brief history of abiotic to biological fuel cells and subsequently, microbial fuel cells is presented. Secondly, the development of the concept of microbial fuel cell into a wider range of derivative technologies, called bioelectrochemical systems, is described introducing briefly microbial electrolysis cells, microbial desalination cells and microbial electrosynthesis cells. The focus is then shifted to electroactive biofilms and electron transfer mechanisms involved with solid electrodes. Carbonaceous and metallic anode materials are then introduced, followed by an explanation of the electro catalysis of the oxygen reduction reaction and its behavior in neutral media, from recent studies. Cathode catalysts based on carbonaceous, platinum-group metal and platinum-group-metal-free materials are presented, along with membrane materials with a view to future directions. Finally, microbial fuel cell practical implementation, through the utilization of energy output for practical applications, is described.

“…Nowadays, many efforts have been devoted to explore various cost‐effective electrocatalyst with high ORR properties, such as the catalysts composed of non‐noble transition metal catalyst (i. e., Mn, Cu, Fe, Co, Ni) or heteroatom catalyst (i. e., N, S, and P) . Among these metals, Co‐based composites with high electrocatalytic activity had been widely studied due to their properties of relative earth‐abundance and low‐cost .…”

To seek an efficient way to enhance the power output and wastewater treatment of microbial fuel cell (MFC), several cobalt‐based composites are successfully synthesized by a facile hydrothermal method under different pyrolysis temperature, and these composites are used as electrocatalyst in air‐breathing cathode of MFC. Different species of nitrogen atom are successfully grafted on the cobalt‐based composites and confirmed by physical and electrochemical analyses. In MFC tests, the maximum power density increases from 577.8 mW m−2 to 931.1 mW m−2 with pyrolysis temperature (except for 1000 °C). These electrochemical tests and high COD removal show that Co/N/C‐900 can rapidly transfer electron via a 2×2 e− transfer pathway, mainly due to the exposure of large electrochemical active area and introduction of the defects of pyridinic−N and abundant oxygen vacancies. Although the power density of MFC with Co/N/C‐900 is 81.1 % of that of commercial Pt/C, the MFC with Co/N/C‐900 is more stable than that of Pt/C, and the power density for Co/N/C‐900 has only a 2.8 % decrease during 25‐cycles operation. The great electrocatalytic activity of the novel Co/N/C‐900 composite exhibits a superior outlook for scale‐up application of MFC in the future.

Green‐Synthesized Nitrogen‐Doped Carbon‐Based Aerogels as Environmentally Friendly Catalysts for Oxygen Reduction in Microbial Fuel Cells

et al. 2018

A green approach to the synthesis of nitrogen‐doped, carbon‐based aerogels with good conductivity and catalytic properties is presented. With the aim to design an easily sustainable process, the starting precursors are selected from abundant waste‐related organic materials. The naturally derived polysaccharide agar acts as the carbon source in a water solution and an amino acid, glycine or lysine, is used as the nitrogen source. Using this synthesis approach, nitrogen defects are created in a 3D porous aerogel. They are shown to act as active catalytic sites for the reaction of oxygen reduction to water as demonstrated by electrochemical measurements. The best performing materials are tested as cathodes in microbial fuel cells for 50 days, in conditions close to those the device would face in a real environment. The glycine‐derived carbon aerogels with the higher content of pyridinic nitrogen exhibit the best performance, as confirmed by several morphological characterizations.
