[quote] At the point where electrical contact was broken, the cell gas was very nearly a stoichiometric mixture of hydrogen and oxygen. Significant hydrogen release will occur because the electrolytic loading was equivalent to many atmospheres of hydrogen gas pressure exposure, but the hydrogen present will inhibit complete Pd unloading. The equilibrium plateau pressure of Pd-D at ~70-100 C is ~300-1000 mbar8, and that the cell pressure is ~1000 mbar since it is an open cell, with at least 2/3 of that consisting of D2. Thus initial unloading to ~0.6 D/M units should occur, and not much more, leaving plenty of hydrogen in the electrode as hydride.[/quote]
Once power is removed disassociation drops off dramatically. Only atoms can translate freely in the lattice so the sudden majority of diatoms Will also oppose unloading. If these atoms were fractional then the diatoms are also fractional and as such store this transitional energy. Fran
