Abstract

Palladium samples electrochemically loaded with hydrogen have been examined in terms of their desorption characteristics using the thermal analysis methods of differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The temperature of maximum desorption is shown to depend on the H:Pd ratio n when loading was carried out at current densities iD≤2 mA cm−2. The molar desorption enthalpy ΔHM, derived from the DSC and TGA data as a function of n (0.48-0.9), was found to be in good agreement with literature values at lower n but deviated at higher n.
