Formation and decomposition pressures of hydrides for Ni0.3Pd0.7, Ni0.5Pd0.5, Ni0.7Pd0.3 and Ni0.9Pd0.1 alloys have been determined by following the thermoelectric power of these alloys as function of hydrogen pressure at 298 K. From the desorption pressures the free energies of hydride formation were calculated. These results combined with literature data are discussed in terms of deviation from an ideal behavior. The dominance of nickel is clearly demonstrated, what could be expected from its large hydride formation pressure in comparison with palladium hydride. The term "excess free energy of formation" is introduced and discussed for the alloy system treated.
