▎ 摘 要
Reduced graphene oxide (rGO) with a specific surface area of similar to 600 m(2)/g has been synthesized and characterized. A series of membrane-electrode assemblies has been fabricated and tested as an element of a fuel cell. In the fabrication of these assemblies, rGO (0-10% of the weight of the Pt/Vulcan XC-72 electrocatalyst) was added to the electrocatalytic composition. The optimum rGO concentration in the active layer of a fuel cell is 5 wt %. At this rGO concentration, the specific power of the fuel cell is at least 20% higher than in the case of the rGO-free electrocatalytic layers.
