Inelastic neutron scattering studies of hydrogen on fuel cell catalysts

Abstract Inelastic neutron scattering (INS) has been used to study the adsorption sites of hydrogen on Pt/C and PtRu/C fuel cell catalysts. At 8×10 4 Pa H 2 pressure the catalysts are at saturation coverage. Increasing the pressure to 4.2×10 5 Pa does not change the spectra, in particular there is no evidence for the on-top site on either catalyst. This data permits an upper limit for the coverage of the catalytically active on-top site to be determined.
