Abstract

The influence of different microstructures and compositional variations on hydrogen absorption by pure Pd, and $Pd_{0.9}Rh_{0.1}$ alloy has been examined from changes in the hydrogen isotherms. The dilute phase solubilities and the plateau pressures are affected by differences in microstructures and compositional variations but the hydrogen capacities at relatively high hydrogen pressures are not affected except for the alloy form which has some phase separation.
