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
Abstract:The proposed research will study a new planar solid oxide fuel cell/electrolyzer design for non-terrestrial applications. The design is based on the Interscience Radial Flow (IRF) planar solid oxide fuel cell technology. The design features the use of… more
Abstract:THE PROGRAM IS DIRECTED TOWARDS THE DEVELOPMENT OF A PLANAR, LOW TEMPERATURE (650C), INTERNALLY REFORMING SOLID OXIDE FUEL CELL (SOFC) POWER SUPPLY THAT WILL LEAD TO THE POWER PLANT HAVING A POWER DENSITY EQUIVALENT TO A MODERN GAS TURBINE AND AN EFFICIENCY… more
Abstract:Aspen Systems proposes an advanced onboard high purity hydrogen production subsystem for fuel cell vehicles. Ultrahigh purity hydrogen will be produced from liquid hydrocarbons utilizing a novel catalytic-membrane-based fuel reformer. The ultra-high purity… more
Abstract:IONOMER MEMBRANES ARE PRESENTLY USED IN DESALINATION, WASTE WATER CLEANUP, CHEMICAL PRODUCTION, AND FUEL CELLS. USE OF A MEMBRANE MATERIAL WITH LOWER IONIC RESISTIVITY THAN IS CURRENTLY AVAILABLE WOULD REDUCE THE ENERGY EXPENDITURE IN ALL OF THESE PROCESSES.… more
Abstract:ONE OF THE CHALLENGES FACING THE COMMERCIALIZATION OF PROTON EXCHANGE MEMBRANE (PEM) FUEL CELL TECHNOLOGY INVOLVES THE REDUCTION OF COST, SPECIFICALLY THAT OF THE ELECTROCATALYST. THE SEARCH CONTINUES FOR NON-NOBLE METAL CATALYSTS WHICH ARE LOWER IN COST AND… more
Abstract:…nefits: In addition to the benefits described above, the resulting designs and technologies can be used by industry and the government in the following applications: variable-speed drives and actuators, variable-speed generation systems, inverters for photovoltaic cells, and … more
Abstract:THIS PROJECT IS AIMED AT IMPROVEMENT IN POWER DENSITY AND LOWERING OF THE CARBONATE FUEL CELL COSTS. THE PRESENT GENERATION OF CARBONATE FUEL CELLS IN QUITE ATTRACTIVE FOR BASELOAD UTILITYAPPLICATIONS BECAUSE OF THEIR HIGH EFFICIENCY, SUPERIOR ENVIRONMENTAL… more
Abstract:THE ATTRACTIVENESS OF CARBONATE FUEL CELL POWER PLANTS CAN BE SIGNIFICANTLY ENCHANCED BY EXTENDING THE LIFE OF THE FUEL CELL STACK BEYOND THE PRESENT DESIGN LIFE OF 40,000 HOURS. LOSSOF SEALING EFFICIENCY OF THE MATRIX DURING THERMAL CYCLING APPEARS TO IMPACT… more
Abstract:COAL-BASED POWER SYSTEMS CAN PROVIDE AN EFFECTIVE MEANS FOR MEETING U.S. ENERGY REQUIREMENTS. COAL-DERIVED AND OTHER HYDROCARBON FUELS CAN POWER HIGHLY EFFICIENT FUEL CELLS IN A WIDE VARIETY OF APPLICATIONS. TO REALIZE THIS OBJECTIVE, ADVANCES MUST BE MADE TO… more

Abstract:… was invented by the principal investigator, is a high quality film deposition technique that can inexpensively and quickly apply yttria stablized zirconia (YSZ) and doped-LaCrO3 thin films in a continuous manner. This technology can be used for the production of 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.
