(Invited) Recent Topics on x-Ray Analysis of Fuel-Cell Catalysts

X-ray analysis utilizing interaction between x-rays and electrons in catalysts provides versatile information on the fuel-cell-catalyst development from basic structural and electronic structural details to reaction and degradation mechanism in in-situ environments.

Quick overview of x-ray analysis methods using various physical phenomena, such as, diffraction, scattering, x-ray absorption, x-ray photo-emission, and latest challenges of their application to the catalyst development for both platinum-based and non-platinum catalysts will be presented.
