The advantages of the PEMFCs are low temperature operation, high conversion efficiency, fast startup, low temperature operation (catalyst alloys may improve catalytic activity for hydrogen oxidation reaction (HOR) and CO poisoning in PEMFC. For cathode ctalysts, Pt-M catalyst alloys (with M transition metals such as Mn, Cr, Fe, Co and Ni) are the most widely studied due to activity for oxygen reduction reaction (ORR) higher than pure Pt. Alloying catalysts improve ORR activity towards reducing oxygen by direct 4-electron reaction withou H2O2 intermediate stage therefore catalytic activity of these alloys may be higher 3-5 times compared to pure Pt / C catalysts. In Vietnam, research on PEMFC fuel cells has not intensively been considered and there are few research groups being studying on direct methanol fuel cell. With desire to develop PEMFC area using direct hydrogen fuel, research on catalytic materials is essential. Therefore, the topic of the thesis was chosen as: “Synthesis and characterization of carbon supported Pt and Pt alloy nanoparticles as electrocatalysts material for proton exchange membrane fuel cell” Scope of thesis: - .
