Abstract
A hydrogen separator is provided, including a porous substrate having a large number of pores communicating from a first surface to a second surface thereof, and having a hydrogen-separating layer disposed on the first surface so that the hydrogen-separating layer has a penetrated portion extending through the pores from the first surface to a particular depth. An average pore diameter at the first surface of the porous substrate is 0.02 to 0.5 μm, a thickness of the hydrogen-separating layer is 1 to 5 μm, and a penetration depth of the penetrated portion is 0.05 to 1 μm, is at least equal to the average pore diameter at the one surface of the porous substrate, and is not larger than one half of the thickness of the hydrogen-separating layer. The hydrogen separator hardly generates defects such as cracks, peeling and the like in the hydrogen-separating layer, is superior in durability, and provides both good hydrogen-separating ability and good hydrogen permeability.
