Abstract
The thermodynamic relationships between the potentials of the palladium‐hydrogen alloys and the known equilibrium properties of the system, palladium‐hydrogen gas, are derived and discussed. A value of 0.048 v for the potential of the saturated α alloy derived from the gas phase data is in substantial agreement with the observed value of 0.050 v. The spontaneous loss of hydrogen from the electrolytically charged alloy of composition, H/Pd∼0.6, to form an alloy of lower hydrogen content shows that there is an unusual free‐energy situation involved in this system. This is discussed and an explanation of the free energy scheme is suggested.Keywords
