A hydrogen permeable composition having a porous ceramic substrate, and a two part membrane adhered thereto. The two part membrane has a metal powder part and a ceramic oxide part, with the metal powder part being Ni, Pd, Pd alloys, Nb, Ta, Zr, V or mixtures thereof. The oxide part is yttria stabilized zirconia, shrinkable alumina, suitably doped cerates, titanate, zirconates of barium or strontium or mixtures thereof, and the hydrogen flux is at least 20 cm.sup.3 per minute-cm.sup.2 at C. in a 100% hydrogen atmosphere. A paste method of forming the composition is disclosed. A method of extracting hydrogen from a gas is also disclosed.
