Steady State Isotopic Transient Kinetic Analysis Study of PEM Fuel Cell Anodes (SPA)
The hydrogen oxidation reaction at Proton Exchange Membrane Fuel Cell anodes is poisoned by part per million levels of carbon monoxide. Pt is the catalyst of choice for the oxidation of pure hydrogen, but it has recently been demonstrated that there is a dynamic equilibrium between CO adsorbed on Pt or Pt/Ru nanoparticles and CO in the gas phase, and that this equilibrium is affected by the competitive adsorption between CO and hydrogen. The purpose of this research is to perform Steady State Isotopic Transient Kinetic Analysis (SSITKA) experiments using the isotopic exchange between 13CO and 12CO to investigate the competitive adsorption of hydrogen and CO on commercial Pt and PtRu catalysts.
