An investigation was made of the permeation of H through various Pd-Ni membranes at temperatures ranging from 300 to 500C, under a pressure difference of 1atm (table 151). Upon increasing the Ni concentration from 0 to 5.5%, there was little change in the diffusivity but the permeability fell sharply upon further increasing the Ni concentration.
