Article Description

Reduced graphene oxide (RGO) with specific surface area of ca. 600 m 2 /g was synthesized and characterized. A series of membrane-electrode assemblies with RGO addition (in amount from 0 to 6 wt%) to electrocatalytic composition based on 40 wt% of Pt on Vulcan XC-72 were fabricated and tested. Pt/Vulcan XC-72 was synthesized using magnetron-ion sputtering in an impulse mode. It was shown that the optimum content of RGO in the fuel cell active layer is ca. 1 wt%. In particular, at this RGO concentration the maximum fuel cell power density is increased by ca. 8.5% in comparison with no-RGO containing electrocatalytic layers.
