In this paper, we concern about CO tolerance of Platinum (Pt)/Graphene Nanosheets (GNS) catalysts dependence of pH. The aim of this research is to investigate relationship between CO tolerance and Pt particle size base on pH dependence and also supporting material effect to CO-tolerance. The research method is modified Hummers and impregnation method to synthesize GNS and Pt/GNS catalysts, respectively. The results show that electrocatalytic measurements of Pt/GNS catalyst prepared at pH = 1 has the highest CO tolerance (69.4 %) under 500 ppm CO level in the hydrogen oxidation reaction among pH = 6, 12.5 and Pt/CB commercial catalyst. It means pH dependence and GNS may be expected to enhance electrocatalytic activity (CO tolerance) of Pt. Furthermore, GNS is possible used as an anode catalyst of Polymer Electrolyte Fuel Cells (PEFCs).

A Current

The potential to improve the CO tolerance of a high temperature proton exchange membrane fuel cell (HT-PEMFC) was investigated by introducing a platinum-ruthenium alloy as anode catalyst. The electrolyte was a H3PO4 doped poly-2,5-benzimidazole polymer (ABPBI). The experiments were carried out at the temperatures between 403 and 443 K with a CO concentration in the H2 feed gas between 0 and 6.5 vol%. The alloy anode catalyst lowers significantly the negative influence of CO in the feed, exceeding the known temperature dependent CO poisoning mitigation in HT-PEMFCs. It was found that the voltage loss of a HT-PEMFC with PtRu anode catalyst was lower than that of a similar cell equipped with Pt anode. The dynamic cell voltage response to a current step was analyzed under CO influence, as well. The PtRu bimetallic anode electrode was found to lower the observed voltage overshoot behavior after a current step, if compared to conventional Pt anode.
