H{sub 2} cold plasma on Pd/H system at low hydrogen pressure

The effect of hydrogen cold plasmas, in negative corona regime, was investigated on the palladium-hydrogen system in the {alpha}+{beta} region at room temperature and H{sub 2} pressures below 0.037 bar. Three independent experimental quantities have been simultaneously measured: hydrogen concentration, electrical resistance, and elongation of the samples. An increase in the above quantities was always observed when plasma was lighted. The ability of an external electric field (the corona discharge) to perturb the thermodynamic state of the Pd/H system was experimentally demonstrated.
