In this Review, we discuss the state-of-the-art understanding of non-precious transition metal
oxides that catalyze the oxygen reduction and evolution reactions. Understanding and …

Polymer-electrolyte fuel cells are a promising energy-conversion technology. Over the last
several decades significant progress has been made in increasing their performance and …

The hydrogen oxidation and evolution reaction (HOR/HER) behavior of carbon supported
metal (Pt, Ir, Rh, Pd) nanoparticle electrocatalysts is studied using the H 2 pump approach …

The hydrogen evolution reaction (HER) plays a key role in a number of technologically
important areas such as water and chlor-alkali electrolysis,[1] metal deposition,[2] …

The stability of carbon-supported electrocatalysts has been largely investigated in acidic
electrolytes, but the literature is much scarcer regarding similar stability studies in alkaline …

The rotating disk electrode (RDE) technique is being extensively used as a screening tool to
estimate the activity of novel PEMFC electrocatalysts synthesized in lab-scale (mg) …

Through a tight collaboration between chemical engineers, polymer scientists, and
electrochemists, we address the degradation mechanisms of membrane electrode …

Pt-based core–shell nanoparticles have emerged as a promising generation of highly active
electrocatalysts to accelerate the sluggish kinetics of oxygen reduction reaction (ORR) in …

A key challenge for fuel cells based on phosphoric acid doped polybenzimidazole
membranes is the high Pt loading, which is required due to the low electrode performance …

This paper discusses the mechanisms of surface area loss of supported platinum (Pt)
electrocatalysts in low-temperature fuel cells. It is argued that submonolayer dissolution of Pt …
