Patent abstract
A gas separator is provided, including a porous substrate made of a first ceramic and a gas-separating layer containing zeolite disposed on the surface of the porous substrate. The gas-separating layer further contains, in addition to zeolite, a thermal expansion coefficient-adjusting material made of a second ceramic having a linear thermal expansion coefficient satisfying a predetermined relationship, so that the difference between the thermal expansion coefficient of the porous substrate and the gas-separating layer can be reduced.
