MEMBRANE FOR PREVENTING HYDROGEN PERMEATION

摘要

The present invention relates to a membrane for preventing hydrogen permeation, which prevents hydrogen from being diffused and discharged by permeation through a membrane and also inhibits embrittlement of materials caused by hydrogen ion diffusion into the materials. Specifically, the membrane is characterized by: preventing hydrogen ion permeation through both the built-in potential of semiconductor layers and the potential applied by a reverse bias, wherein the semiconductor layers are respectively doped with p-type and n-type impurities; primarily preventing hydrogen molecule permeation by an adsorption layer for adsorbing hydrogen molecules; and secondly preventing hydrogen molecule permeation and also inhibiting embrittlement caused by hydrogen using the adsorption layer made of conductive materials as an applied electrode of the reverse bias, and simultaneously by causing ionization of hydrogen adsorbed inside the adsorption layer.
