Abstract:Presently available technology for converting logistic fuels to hydrogen for use in fuel cells is unsatisfactory in three fundamental ways. First there is the problem that the hydrogen that is produced in the initial fuel gasification step contains impurities… more
Abstract:… achieve gravimetric energy density of 2.5Wh/kg and volumetric energy density of 2500 kWh/M(3), while also having good hydrogen sorption kinetics, long cycle life, resistance to poisoning and low cost. Such a H-storage system will make the PEM and other types of fuel … more
Abstract:Proton exchange membrane (PEM) fuel cells provide significant advantages over conventional power systems. They operate at very high efficiencies (greater than 50% direct conversion and at system efficiencies which can exceed 40%), generate no emissions, are… more
Abstract:CARBONATE FUEL CELL POWER PLANTS OFFER THE MOST EFFICIENT AND ENVIRONMENTALLY SUPERIOR OPTION TO GENERATE ELECTRICITY FROM NATURAL GAS, COAL GAS, AND OTHER HYDROCARBON FUELS. TO REALIZE THE GREATEST COMMERCIAL POTENTIAL OF THESE POWER PLANTS, ADVANCES ARE… more
Abstract:This program will demonstrate the fabrication of ultra lightweight/high performance composite annular electrodes incorporating the reliability, via strength and toughness, necessary to facilitate efficient, simple assembly of low cost PEM fuel cells for… more
Abstract:Currently, a 300 watt fuel cell stack of bipolar design projects a power density of about 40 watts per kilogram of system, excluding fuel and fuel tankage. In contrast, a battery of identically performing fuel cells which uses the concept of a single sheet… more
Abstract:The overall objective of this SBIR project is to demonstrate the feasibility of a new, all solid state, solid oxide fuel cell (SOFC) technology to generate electric power in a reliable and cost effective manner from air (or oxygen) and hydorgen (or low… more
Abstract:…. This performance advantage will be further leveraged by the use of new electronic switches (Mats) which offer substantially lower conduction losses than traditional devices. The core technology can be applied to motor control, alternate energy sources (such as fuel … more
Abstract:Fuel cells bring about the direct conversion of stored chemical energy to electrical energy having efficiencies much higher than those of Carnot engines. So far, the proton exchange membrane (PEM) fuel cell system is the leading candidate fuel cell power… more
Abstract:… or smaller vehicles (both commercial and military applications), is well suited to hybrid vehicles, and industrial motor control. It offers efficiency improvements in any DC to AC converters, including those for the conversion of alternate energy sources (such as fuel … more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
