Hydrogen gas is one of the most important alternative energy sources and indispensable to operate fuel cells. Using conventional reforming technique of some kinds of hydrocarbons, or alcohols, it is easy to obtain hydrogen gas. In this case, however, separation of hydrogen from other byproducts is not easy. We prepared silver nanoparticles by sonochemical reduction of silver complex, molded them in the film, and tried to develop novel hydrogen selective permeation membrane. Silver-ethylenamine complex was used as precursor of colloidal silver. In the presence of polyethyleneglycol monostearate, sonochemical reduction of silver complex successfully proceeded and formed yellowish transparent solution including silver nanoparticles. Silver thin films were prepared by immobilizing them on the surface of AAO mesh by electrophoresis technique. Sonochemical immobilizations of Ag onto the AAO mesh were also carried out. We will report the property of the membrane for the selective permeation of hydrogen gas.
