Electricity generation, energy storage, and microbial-community analysis in microbial fuel cells with multilayer capacitive anodes

Carbon material‐based anodes in the microbial fuel cells

“…The N‐doping strategy was also used for carbon‐based ternary composites for further improving the MFC performance. The developed anode materials including N‐CNT/PANI/MnO 2 and S/N‐CNT/PANI/MnO 2 displayed better MFC performance, compared with the corresponding binary counterparts, strongly confirming their better synergistic effects 127,128 …”

Carbon‐Based Composites as Anodes for Microbial Fuel Cells: Recent Advances and Challenges

“…More importantly, this anode exhibited an excellent power storage capability by releasing 16172.6 C m À 2 over 60 min of charging, paving the way for the application in a micro-system of low-power intermittent operations. [97] Due to the high sensitivity to biological species and πelectron conjugated system, another conductive polymerpolypyrrole (PPy) is also widely applied in CNT-based MFC anode materials to introduce more positive surface charges, faster electron transfer between bacteria and the anode, and stronger adhesion to the microbes. [98][99][100] More importantly, PPy can reduce the cellular toxicity of CNTs thus promoting the growth and activity of electricigens and enhancing the electricity generation of the MFCs.…”

A Novel Design Portable Plugged-Type Soil Microbial Fuel Cell for Bioelectricity Generation

“…or Pseudomonas spp. [9,10,13]. Therefore, it can be assumed that the paddy soil used in this study contained the same species.…”

“…Most recent studies have extensively focused on optimizing the SMFC configurations such as single-chamber MFC with or without membrane, column-type MFC, and dual-chamber MFC with proton exchange membrane (PEM). Some studies have attempted to decrease the internal soil resistance or electrode spacing; addressed in electrode material innovation such as using a TiO 2 , Ag@g-C 3 N 4 nanostructure, developed multilayer capacitive anodes to improve anode capacity, or the electricity generation performance [4,8,[10][11][12][13][14][15][16]. Other studies have attempted to enhance the performance by adding carbon fiber into the soil to increase soil conductivity, accelerated the transport of substrates in the soil, and developed mixed culture electrochemically active biofilms [7,10,17]; however, there has still been little research reported for portable SMFC construction.…”
