For polymer electrolyte fuel cells (PEFCs), platinum nanoparticles supported on carbon black (Pt/C) serve as the commonly used hydrogen anode catalyst, exhibiting high activity for the hydrogen oxidation reaction (HOR), while the carbon support is su

The performance and stability of polymer electrolyte membrane fuel cells (PEMFCs) are directly affected by the distribution of water molecules inside the membrane. In this study, coherent anti-Stokes Raman scattering (CARS) spectroscopy was used to m

The CO-tolerance mechanism of a carbon-supported Pt-Fe alloy catalyst with two atomic layers of stabilized Pt-skin (Pt2AL–PtFe/C) was investigated, in comparison with commercial Pt2Ru3/C (c-Pt2Ru3/C), by in situ attenuated total reflection Fourier

We prepared monodisperse Pt2Ru3 nanoparticles supported on carbon black and Sb-doped SnO2 (denoted as Pt2Ru3/CB and Pt2Ru3/Sb-SnO2) with identical alloy composition and particle size distribution by the nanocapsule method. The activities for the hydr
