Integrating PGM‐Free Catalysts into Catalyst Layers and Proton Exchange Membrane Fuel Cell Devices
Advances in Materials, 2019While proton exchange membrane fuel cells (PEMFCs) continue to expand into commercial markets, there is still pressure to decrease cost. One of the largest opportunities to reducing cost is to reduce the amount of platinum‐group metal (PGM) catalysts ...

ECS Meeting Abstracts
Hydrogen, known for its high gravimetric energy density and low environmental impact, is widely regarded as a promising low-carbon energy carrier. The production of hydrogen via water electrolysis offers a valuable opportunity to efficiently utilize renewable energy resources – both as a storage and transport medium and to produce hydrogen that is a

Decoupling the Synergy Between PGM and PGM‐Free Moieties toward Oxygen Reduction Reaction
SmallAbstractRecently, coupling the conventional low Pt‐group‐metal (low‐PGM, LP) and emerging PGM‐free (PF) moiety to form a composite LP/PF catalyst is proposed to be an advanced strategy to improve the intrinsic activity and stability of oxygen reduction reaction (ORR) catalysts.

This contribution analyzes the nature of GEMF 52/PGM XXIVa, a third century papyrus fragment with incomplete instructions for some kind of oracular consultation. We provide context to this papyrus through comparison with other Greek and Egyptian divinatory texts and artifacts, to understand the process of consultation and its methods.
