Electronic metal-support interaction enhanced oxygen reduction activity and stability of boron carbide supported platinum.
Colleen Jackson,Graham Smith,Graham Smith,David W. Inwood,Andrew S. Leach,Penny S. Whalley,Mauro Callisti,Tomas Polcar,Andrea E. Russell,Pieter Levecque,Denis Kramer +10 more
TL;DR: Platinum nanoparticles supported on graphite-rich boron carbide show a 50–100% increase in activity in acidic media and improved cycle stability compared to commercial carbon supported platinum nanoparticles, showing that purely electronic metal-support interactions can significantly improve oxygen reduction activity.

Edmund J. F. Dickinson,Graham Smith +1 more
- 28 Oct 2020
TL;DR: Theoretical models used to describe the proton-conductive membrane in polymer electrolyte membrane fuel cells (PEMFCs) are reviewed, within the specific context of practical, physicochemical simulations of PEMFC device-scale performance and macroscopically observable behaviour.

Membrane electrode assemblies based on porous silver electrodes for alkaline anion exchange membrane fuel cells
TL;DR: In this article, porous silver membranes were investigated as potential substrates for alkaline fuel cell gas transport electrodes by both electrochemical half-cell measurements in aqueous KOH electrolyte and production of fuel cells utilising an anion-exchange polymer electrolyte.
