Hydrogen storage is one of the great challenges limiting the commercialization of polymer electrolyte membrane (PEM) fuel cell technology for automobile and unmanned vehicles. Full commercialization is dependent upon the development of compact and cost competitive hydrogen storage technologies with longer drive range and capability of meeting practical performance targets. Researchers at the University of Hawaii have developed novel magnesium boride based materials that undergo rapid, reversible hydrogenation at significantly lower temperatures and pressures than current state-of-the-art pure MgB2 material.
This invention provides a potential pathway for a solid-state hydrogen storage system suitable for onboard PEM fuel cell powered vehicles that is safer and cheaper than the high pressure or liquid hydrogen alternatives currently available on the market.
