We have already shown that Pt-CeO2sputtered catalyst exhibits high specific power (thousand-times higher power per mg of platinum and only few times lower power density in comparison with Pt reference catalyst) so such material could be an appropriate for PEMFC anode (HOR) [2,3,4].
Presented work is aimed for understanding the role of Pt and Ce chemical states and Pt-Ce interactions in HOR and ORR catalytic activity investigated in-situ using X-ray Absorption Near Edge Structure (XANES). Additionally, the performance and endurance of this catalyst obtained through direct testing in fuel cell test station are presented. Then, morphology determined by scanning electron microscopy and photoelectron spectroscopy results is shown.
