Özet

In this study, two different Pt catalysts were synthesized by using 1,5-dimethyl platinum cyclooctadiene and platinum(II)acetylacetonate precursors on graphene nanoplates (GNPs). Supercritical carbon dioxide deposition technique was used in the catalyst synthesis. Electrochemical and physicochemical analyzes were performed on the synthesized materials. As a result of the PEM fuel cell tests, the catalyst prepared by using Pt(COD)Me2 provided better current (332.7 mA/cm2 ) and power density (199.4 mW/cm2 ).
