PEMFC Cathode Hydrogen Evolution Reaction (HER) 2H+ + 2e- H2 Oxygen Reduction Reaction (ORR) O2 + 4e-  2O2- Overall Balanced Cathode Reaction 4H+ + O2 + 4e-  2H2O

TMCs TMCs have been demonstrated to be catalytically active for HER and ORR.1,2 Advantage of nano-scale platinum. 1. S. Wirth, F. Harnisch, M Weinmann and U. Schroder, Appl. Catal. B, 2012, 126, 225. 2. G. He, Z. Yan, X. Ma, H. Meng, P. K. Shen, and C. Wang, Nanoscale, 2011, 3, 3578.

Synthesis Salt Flux method for TMCs Incipient Wetness Impregnation to deposit platinum

Characterization X-Ray Diffraction (XRD) to confirm composition Transmission Electron Microscopy (TEM) to confirm morphology Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) to confirm platinum concentrations Linear Sweep Voltammetry (LSV) Current density is related to catalytic activity

XRD

TEM

ICP-OES

LSV-HER, Normalized Current Density at -0.144 V

LSV-ORR, Normalized Current Density at 0.456 V

Conclusion Pt deposited TMCs for groups 4-6 can be cleanly synthesized Pt/WC and Pt/Mo2C showed highest current density for both HER and ORR Several other Pt/TMCs show increased catalytic activity over Pt/C control.
