The use of Pt-based cathode catalyst materials hinders the widespread application anion exchange membrane fuel cells (AEMFCs). Herein, we present a non-precious metal (NPMC) material based on pyrolysed Fe and Co co-doped electrospun carbon nanofibres (CNFs). prepared are studied as oxygen reduction reaction (ORR) evolution (OER) catalysts in alkaline acidic environments. High activity towards O...

Hollow cathode plasma sputtering is an advantageous method of preparing catalysts in the form thin oxide films on supports. Such are particularly suitable for processes such as catalytic total oxidation volatile organic compounds (VOCs), representing economically feasible and environmentally friendly VOC abatement. Catalysts with Ni:Co molar ratios 1:4, 1:1, 4:1 were prepared stainless-steel me...

Scaling up microbial fuel cells (MFCs) requires a better understanding the importance of the different factors such as electrode surface area and reactor geometry relative to solution conditions such as conductivity and substrate concentration. It is shown here that the substrate concentration has significant effect on anode but not cathode performance, while the solution conductivity has a sig...

An inexpensive activated carbon (AC) air cathode was developed as an alternative to a platinum-catalyzed electrode for oxygen reduction in a microbial fuel cell (MFC). AC was cold-pressed with a polytetrafluoroethylene (PTFE) binder to form the cathode around a Ni mesh current collector. This cathode construction avoided the need for carbon cloth or a metal catalyst, and produced a cathode with...
