Summary
One of the challenges for the commercialization of polymer electrolyte fuel cells (PEFCs) is the development of new cathode catalysts for the oxygen reduction reaction (ORR) that exhibit superior activity and durability than conventional platinum (Pt) catalysts (Pt/C).
Here, Zaenal Awaludin, Takeo Ohsaka, and colleagues at Department of Electronic Chemistry report the development of TaOx (tantalum oxide) nanoparticles capped with Pt nanoparticles (Pt/TaOx) that possess a higher activity and durability than a Pt catalyst alone.
