The high power impulse magnetron sputtering (HiPIMS) process is used to incorporate catalytic nanoclusters of platinum into microporous carbon. Such a process leads to an enhancement of the Pt species%26apos; penetration into the porous medium, as evidenced by Rutherford backscattering spectroscopy analysis. Each sample of catalyzed porous carbon is tested as a cathode of a proton exchange membrane fuel cell (PEMFC). An increase of 80% at 0.65 V of the PEMFC power density for a low catalyst loading of 0.02 mg cm(-2) highlights the use of the HiPIMS process versus the conventional dc magnetron sputtering process.
