Summary on Grant Application Form |
|
In this project we will extend in situ X-ray absorption spectroscopy (XS) to more realistic models of proton exchange membrane (PEM) fuel cell systems. The cell to be designed will enable measurements to be conducted at elevated temperatures and under conditions of reactant gas flow which are representative of the working PEM fuel cell. The anode reactions characteristic of reformate and direct methanol fuel cells will be examined for Pt, PtRu, PtWOx and PtMo carbon supported electrocatalysts. Such investigations will aid in the understanding of the bifunctional character of the alloy catalysts in providing CO tolerance for reformate fuelled cells and preventing CO poisoning of direct methanol fuel cells. The cathode reaction, oxygen reduction, will be investigated for Pt, PtCr, PtTi and PtCo carbon supported electrocatalysts. In the case of Pt the effect of particle size under PEM conditions will be investigated, while for the alloys the stability of the parameters (lattice contraction and d-electron density of the Pt in the particles) which define the catalyst structure under he conditions of oxygen reduction will be investigated.
