Abstract: The present invention relates to a method for protecting a hydrogen separation membrane from particulate contaminants in the process of producing or purifying hydrogen by using the separation membrane. The protection layer, wherein a cermet is formed by coating a ceramic and a metal able to cause surface movement of hydrogen molecules and hydrogen atoms to the surface of the separation membrane, plays the role of blocking contact between the separation membrane and particles (contaminant or catalyst) contained in the gas. In this way, it is possible to improve the durability of the hydrogen separation membrane and to minimize effects on the hydrogen permeability of the separation membrane.
