Abstract

Hydrogen uptake and discharge by thin metallic films under potentiostatic control was studied using x-ray diffraction at the National Synchroton Light Source (NSLS). The formation of metal-hydrogen phases in Pd, Pd-capped Nb, and Pd/Nb multilayer electrode structures was deduced from x-ray diffraction data and correlated with the cyclic voltammetry (CV) peaks. The x-ray data were also used to construct a plot of the hydrogen concentration as a function of cell potential for a multilayered thin film.
