Abstract: A device for separating hydrogen from gaseous mixtures containing it or for purifying gaseous hydrogen, comprising an outer casing (2) fiIled with a plurality of tubes (3) made of a suitable palladium based alloy, which tubes are closed at one end (4). The tubes are fixed in substantially seal-tight manner, at the open end side (5), to a part at least of a base (6) made of a metal alloy, the composition of which is such that its expansion coefficient in hydrogen is substantially equal to that of the alloy of the tubes. The base can be integrally formed and made of the above-mentioned alloy, or it can comprise a ring of substantially the same composition as that of the tubes adhering thereto by way of an autogenous soldering.
