A palladium alloy composite membrane for permeances of hydrogen and preparation thereof

摘要

The present invention relates to a production method thereof and a palladium alloy composite for hydrogen gas separation membrane, and more particularly, to performing a pre-treatment step of dispersing and heat treating the porous metal support surface of nickel fine powder mitigate the degree pore size and roughness of the support, to give further support and a palladium alloy layer between, the sol-the introduction of the silica thin film by the gel method by domoham the thermal stability of the metal support and a palladium alloy layers, as well as, the palladium alloy layer introduction method, the support to do the vacuum plating method so as to not only prevent the pores from the surface deep into forming a thin film layer thickness of the plated layer to less than 2 ㎛ relates to a method of manufacturing the hydrogen gas separation palladium alloy composite membrane for which thereby improves selection permeable to hydrogen gas.
