Regenerable Sorbents for Hot Fuel Gas Desulfurization for Fuel Cell Applications
TechnologyOver the past two decades, significant effort has been devoted by the DOE, academic groups, and industry to develop regenerable sorbents for the desulfurization of fuel gas streams (particularly coal-derived) at high temperatures. To date, no bulk oxide or mixed oxide sorbent has been found that achieves the desired criteria for high reactivity,...

Novel Catalysts with Substantially Reduced Metal Content and Undiminished Activity
SummaryResearchers at Tufts University have discovered a novel method to make effective catalysts for fuel cells using only a fraction of the precious metals typically used, substantially lowering manufacturing costs. The resulting catalyst is virtually free of microcrystalline metal particles and just as efficient as traditional catalysts.BackgroundFuel...
