Abstract

This study proposes using the modified polyol synthesis method to obtain state-of-the-art bimetallic catalysts for PEMFCs. One-step and multi-step implementation of the polyol process in an acceptable temperature range, without any hard-to-remove surfactants, requires no complex equipment and allows for the efficient reduction of precursors to nanoparticles. The high-performance catalysts based on the PtCu nanoparticles were obtained by the one-step strategy. These catalysts exhibited an excellent ORR activity that was twice as high as that of commercial Pt/C. The multi-step strategy was used to obtain the gradient-architecture PtCu nanoparticles with an increased stability during stress testing. HR-TEM, EDX, STEM, XRD, and TXRF were used for a detailed study of the catalysts’ microstructure. The key feature of this study consists in monitoring the materials’ characteristics at different stages of their evolution: from the moment of synthesizing them to the state corresponding to the completion of certain stages of the electrochemical measurements.
