چکیده انگلیسی
A comparative study between PtAu/MWCNT and Pt/C (commercial) as cathodic electrocatalyst of H2/O2 fuel cell is performed. PtAu/MWCNT is synthesized using the reverse microemulsion method and this procedure is scaled-up in order to prepare membrane-electrode assemblies for fuel cells with an active area of 9Â cm2. Those electrocatalysts are characterized by both physicochemical techniques and electrochemical measurements to evaluate their catalytic activity for ORR (Oxygen Reduction Reaction). In the half-cell study, PtAu/MWCNT show higher kinetic current density as cathodic electrocatalyst compared with Pt/C. Likewise, in a fuel cell hardware the maximum power density is significantly higher for PtAu/MWCNT cathode (625Â mWÂ cmâ2 at 0.426Â V) when compared with Pt/C anode (355Â mWÂ cmâ2 at 0.499Â V).
