4d electron layer lacks two electrons, it can generate a non-stable chemical bond with hydrogen (this reaction of palladium and hydrogen is reversible), in the action of palladium, hydrogen is ionized as a proton whose radius is 1.5 × 1015m, and the crystal of palladium

The grid constant is 3.88 × 10-10m (20 ℃), therefore it can be through 15crmo alloy tube, under the action of palladium proton again joined with electrons and re-formed hydrogen molecules, from 15crmo alloy tube to another.

Mechanical performance is poor, easy oxidation when high temperature, re-crystallization temperature is low, easy to make 15crmo alloy tube deformed and brittle, therefore cannot be made with pure platinum through the membrane.
