Abstract
Metal-nitrogen-carbon (M-N-C) compounds such as Fe-N-Cs are currently the most promising platinum group metal free catalysts for oxygen reduction. Regarding the overriding goal of reducing PEM fuel cell production costs by reducing the amount of platinum, the use of Fe-N-Cs as catalytic active support is investigated in this study. Activity and stability of Pt in different contents on a commercial Fe-N-C is compared to Pt on a typical carbon black. Pt nanoparticles are well-distributed on both support classes. However, electrochemical surface and mass activity of Pt is lower on Fe-N-C compared to carbon black. Although Pt does not profit in any catalytic matter from interaction with Fe-N-C, the Pt/Fe-N-C in total has a boosting effect on ORR activity being important for future strategies to lower the Pt content in PEM fuel cells.
