Study of ORR kinetic on Pt/C at the presence of super paramagnetic of Fe3O4 nanoparticles in PEMFC

Ion-exchange polymer membrane fuel cell (PEMFC) is as power source that fed by hydrogen gas and produce water. Electrochemical oxygen reduction reaction (ORR) is one of the most important reactions in the fuel cell energy conversion. ORR in acidic condition is four electron reaction of oxygen to water. Oxygen is a powerful oxidizing agent and is actually responsible for the extraction of energy from the fuel. But sluggish kinetic of ORR in Fuel cell is a problem. In this paper the role of super paramagnetic Iron oxide nanoparticles with different loadings, at the presence of commercial Pt/C was evaluated via conventional three electrode system and electrochemical tests such as Cyclic Voltammetry, Rotating disk electrode (RDE), Chronoamprometry
