Summary: By utilizing a novel catalyst containing both Ir nanoparticles and Ir single-atom sites, the issue of CO poisoning in proton-exchange membrane fuel cells (PEMFCs) has been successfully addressed, leading to excellent H-2 oxidation activity and CO electro-oxidation activity. The interplay between Ir nanoparticles and Ir single-atom centers confers the catalyst with improved performance in tolerating CO in H-2/CO mixture gas compared to the current best PtRu/C catalyst.

Summary: In this study, a novel core-shell structured Pt@NC/C catalyst was developed, with ultrafine Pt nanoparticles as the core and ultra-thin nitrogen-doped carbon layers as the shell. The catalyst exhibited excellent activity for the alkaline hydrogen oxidation reaction, with high mass activity and specific activity. Moreover, it showed good anti-CO poisoning ability. The interaction between Pt and the carbon layer enhanced hydroxyl adsorption, promoting reaction kinetics and improving CO resistance. This work provides a facile and feasible strategy for designing efficient and CO-resistant Pt-based catalysts.

Summary: The development of highly active anode catalysts with excellent CO tolerance is crucial for the commercialization of proton exchange membrane fuel cells (PEMFCs). In this study, a CO-tolerant catalyst (Pd-WO3/C) was successfully synthesized by loading Pd nanoparticles on WO3 using an immersion-reduction route. The optimized 3Pd-WO3/C catalyst showed remarkably high power density and quick recovery after CO-contamination removal, surpassing the performance of Pt/C or Pd/C catalysts. The enhanced HOR activity and CO tolerance of 3Pd-WO3/C can be attributed to the optimized interfacial electron interaction and a novel synergetic catalytic mechanism.

Summary: This study investigates deuterium separation using two types of AFCs with different catalysts and finds a mass transportation limitation at Ru catalyst leading to a decrease in voltage. The slow reaction rate of D-2 gas on Ru catalyst is supported by AC impedance measurements. Experimental results show that deuterium is diluted with Pt catalyst but concentrated with Ru catalyst, possibly due to differences in adsorption energy on the catalyst surface.
