Equations for the entropy production and free-energy dissipation for iso-hydrogen-content
hysteresis are derived for metal hydrides. These values should be equal to those previously
derived for isobaric, thermal and isothermal, pressure hysteresis. Experimental data for iso-
hydrogen-content hysteresis are obtained for the palladium-hydrogen system, and these
results confirm that, to within experimental error, the values of entropy production and free-
energy dissipation are equal to the values from the other two methods of measuring …
