Magnetically Modified Metals and Metal Alloys for Hydride Storage

CTCN Keyword Matches:

Background:Magnetic field effects in electrochemical systems arise through transport and kinetic effects of paramagnetic reactants products or intermediates. Researchers at the UI have shown that magnetic composite modified electrodes where the magnetic field is supplied by ferromagnetic microparticles without an external field can provide substantial improvements to a large variety of electrochemical systems.Technology Description:This technology is a solid state hydrogen storage material that has been demonstrated to improve the kinetics of electron transfer in an electrode. Permanent magnetic microparticles are incorporated onto the surface of an electrode material and facilitate transfer of hydrogen atoms across the electrode-electrolyte interface. Magnetic modification of palladium (Pd) surfaces has been shown to significantly improve the rate of hydrogen storage. The technique may find application for other hydrogen storage metal hydrides AB5 and AB2 and other hydrides.Applications:1) Fuel cellsPatent Status:Pending
