Some metals (Pd, Ni, ..) or their metal alloys “solve” large amounts of hydrogen, based on adsorbtion and absorption.
Adsorption is here seen as a kind of loose chemical bond between metal and hydrogen – on the surface, while the absorption is a deposit of hydrogen in lattice cavities.
It is known from investigations (DE 10 2008 047 334 B4) that adsorption of hydrogen on the surface of Pd/Li-alloys leads to an RT-Superconductor( Pd/Li/H) on the surface.
Inspired by. Fig. 3 from https://arxiv.org/pdf/1201.0139v1.pdf , the same picture of current-flow results when the massiv Superconductor – in Fig. 3 – is replaced by a superconductive coated conductor.
The result is a strongly different electron density in the environment of absorbed hydrogen in lattice cavities (for conductor and superconducting layer). The electron density in the conductor / superconductor interacts with the shell electron of the hydrogen, which is pushed by the repulsion of similar charges towards the nucleus. At a current density of 10exp6 A / cm2 in the superconducting layer, e-capture occurs.
