Summary: Optimizing the structure of electrode materials is an effective strategy for designing high-power microbial fuel cells (MFCs). In this study, a three-dimensional (3D) nitrogen-doped multiwalled carbon nanotube/graphene (N-MWCNT/GA) composite aerogel is synthesized as the anode for MFCs. The N-MWCNT/GA electrode has a macroporous hydrophilic structure and low intrinsic resistance, enabling high-density loading of microbes and facilitating extracellular electron transfer, resulting in high-power output performance of the MFC. This research demonstrates the potential of 3D N-MWCNT/GA anodes for high-power MFCs in different environments by optimizing their chemical and microstructures.

Summary: This study reports the development of a co-laminar flow microbial fuel cell (MFC) with microfabricated single-walled carbon nanotube (SWCNT) electrodes using electrophoretic deposition. The study investigates the effects of flow channel height and shear stress on the performance of the MFC, showing that adjusting both parameters can improve power density but decrease fuel utilization. The developed MFC with its high power density has great potential for research and applications compared to traditional metal-based electrode MFCs.

Summary: This study reveals that a carbon material derived from Trapa natans husk has the potential to improve the power density of plant microbial fuel cells (PMFCs). The enhanced power density is attributed to its high surface area and the presence of oxygen-containing groups, which enhance hydrophilicity and microbial attachment, reducing activation polarization. Furthermore, it is shown that this low-cost electrode material can be applied in a PMFC-supercapacitor system for sustainable power generation and energy storage.

Summary: One of the most important challenges in the development of proton exchange membrane fuel cells is to select an efficient electrocatalyst support that can minimize changes in the electrochemical surface, electronic conductivity, and activity while providing a low loading of active metal. In this study, carbon nanotube arrays (CNTAs) grown directly on commercial gas diffusion layers (GDLs) were utilized to form electrodes with a microporous layer. The catalytic layer was formed within the microporous layer by controlled impregnation of CNTAs with Pt-precursor and subsequent reduction of platinum particles. The resulting electrode demonstrated increased electrical conductivity and improved stability and service life.
