Radiolytic Preparation of Electrocatalysts with Pt-Co and Pt-Sn Nanoparticles for a Proton Exchange Membrane Fuel Cell
Figure 7
Polarization and power density plots at 60°C for PEMFCs using Pt-Co/VC, Pt-Sn/VC, and Pt/VC (HiSpec 4000) anode catalysts prepared by RIR. Test conditions: back pressure, PO2 = 0 kPa, PH2= 0 kPa; O2 and H2 gases flowing at 200 SCCM and 400 SCCM; the catalyst loading was 0.2 mg of Pt at the cathode and 0.4 mg of Pt-M or Pt/cm2 at the anode; Tcell = 60°C.
