3、 Working principle
Hydrogen molecules and atoms are the smallest molecules and atoms among all chemical elements. If we consider the single crystal structure of palladium as a face centered cube, the eight corners of the cube are occupied by eight palladium atoms, and the central part of the six faces is occupied by six palladium atoms. In the dense packing of palladium atoms, only hydrogen atoms that can dissociate on the surface of the palladium tube can pass through, while the atoms and molecules of other elements have diameters larger than the gaps in the dense packing of palladium atoms, so they cannot pass through. The palladium diffusion method for purifying hydrogen utilizes this principle by diffusing hydrogen through a palladium tube to determine its purity.
