The composite membranes based on Group 5 metals are capable of H 2 separation with the high speed and infinite selectivity. The chemical and thermal stability are critical issues for the application of such membranes in the field of hydrogen energy. In order to understand the degradation mechanisms,
## Abstract Measurements of the permeation rate of electrolytic hydrogen through steel membranes have shown that compounds of P, As, Sb, S, Se, and Te enhance the entry of hydrogen into the steel only under conditions resulting in the formation of hydrides of hydrides of these elements. It may be p
