Magnetically Modified Metals and Metal Alloys for Hydride Storage
Thistechnology uses a magnetic micro-particle coating to improve solid statehydrogen storage material. Commercially available magnetic micro-particles werecovered in a thin silane coating to make them chemically inert while still ableto generate a magnetic field. These particles were then applied to the surfaceof a palladium electrode to aid the transfer of hydrogen at the surface. This modification lowered the amount ofcurrent required to electrochemically store hydrogen in an electrode, therebylowering the energy cost of the system. This technology also showedimprovements in the rate of hydrogen adsorption and discharge, making it betterthan non-modified electrodes in storing hydrogen for full cell technologies.While this technology was applied to a palladium electrode, it is predictedthat this technology can be applied to other metal hydrides that are morewidely used.
