| Dec 7, 2012 at 16:56 | comment | added | permeakra | Metallic (Interstitial) hydrides are quite well-knows, and proximity of Delta G (Free Energy) of formation for some hydride to zero is not that strange. What is much more interesting, is easiness, with which protons travels through solid palladium. This is a thing that hard to understand. | |
| Dec 7, 2012 at 16:51 | comment | added | Ben Norris | There is an equilibrium process, then, that can be manipulated by changing the conditions (for example low pressure vs. high pressure). I just don't know how it is done. | |
| Dec 7, 2012 at 14:42 | comment | added | Cargo | That seems a reasonable conclusion and is what I assumed until I read that Palladium hydride readily releases H₂ by the reverse process of hydrogen absorption. | |
| Dec 7, 2012 at 12:32 | comment | added | Ben Norris | The one-line answer would be that the two Pd-H bonds that form must be lower in energy, but right now I don't have anything to back that up. | |
