We examined the durability of a carbon-supported Pt-based Co alloy catalyst (Pt–Co/C) during voltage cycling tests under supersaturated humidity conditions to simulate events such as flooding. The voltage cycling tests were conducted from 0.4 V to

In order to prevent coalescence of platinum clusters on a carbon particle surface, new platinum catalysts covered with a thin carbon layer were proposed. The catalysts were produced by evaporation above the eutectic point between carbon and platinum.

High-resolution transmission electron microscopy (HRTEM) of carbon particles has been carried out at 80 °C in saturated water vapor, to evaluate any structural alterations. Amorphous particles or microcrystallites of carbon based on the graphitic st

The electric field effect on Pt cluster-carbon particle nanosystem for the polymer electrolyte fuel (PEFC) cell has been directly demonstrated by two experimental methods. The Pt- C catalyst was flown to the plus plate about 830 V/cm2 electric field

The effects of H2 and O2 gases on the typical fuel cell catalyst of Pt clusters on carbon particles (Pt on C) were examined using a special side-entry sample holder for high-resolution transmission electron microscopy. The holder can be used to trans
