Resumo

PtRu and PtRuMo electrocatalysts supported on N-doped graphene nanoplatelets (N-GNPs) were synthesized by a polyol method and utilized as anodes in polymer electrolyte membrane fuel cells (PEMFCs) to measure their CO tolerance and stability. A higher structural stability of the N-GNP supported catalysts, presenting a lower metal loss and a lower particle growth than PtRu/C was observed. Tests in PEMFCs indicated both a higher CO tolerance and a higher electrochemical stability of N-GNP supported PtRu and PtRuMo catalysts than a commercial conventional carbon black (CB) supported PtRu.
