Hydrogen Solubility in Metal Membranes: Critical Review and Re-Elaboration of Literature Data.

ABSTRACT: This study undertakes a thorough examination of hydrogen solubility within various metal-alloy membranes, including those based on palladium (Pd), vanadium (V), niobium (Nb), tantalum (Ta), amorphous alloys and liquid gallium (Ga). The analysis aims to outline the strengths and weaknesses of each material in terms of solubility and permeability performance. The investigation began by acknowledging the dual definitions of solubility found in literature: the "secant method", which calculates solubility based on the hydrogen pressure corresponding to a specific sorbed hydrogen loading, and the "tangent method", which evaluates solubility as the derivative (differential solubility) of the sorption isotherm at various square root values of hydrogen partial pressure. These distinct
