Although oxygen-conducting ceramics are used as electrolytes in solid oxide fuel cells (SOFCs), their requirements for high temperature operation cause material… more
Abstract:1. A conceptual baseline design of a hydrogen supply system with a on/off capability will be prepared for delivering hydrogen in increments of up to 10g/hour with a total capacity of 120g hydrogen. This baseline design will be based upon a solid state hydrogen reactant mixture with a yield of 8% by… more
Abstract:…. At a projected maximum rotation speed of 58,000 rpm, a 29.5 pound FWUPS module provides 15 minutes of energy at an output power level of 2Kw. This assumes the FWUPS spins down from full speed to half speed during discharge. A flywheel is superior to batteries or fuel … more
Abstract:The proposed research examines the feasibility of using solid oxide fuel cell (SOFC) for shipboard electric power generation by substituting new ceramic anode materials able to operate with logistic fuels. These anodes would allow the SOFC to operate witha… more
Abstract:Fuel cells promise unique siting characteristics and operating benefits which can help extend or increase the availability of electrical power in rural communities. Some of these advantages include: availability in small sizes, modularity, fuel efficiency,… more
Abstract:THE OBJECT IS THE DEVELOPMENT OF A MINIATURE HYDROGEN GENERATOR FOR SMALL PROTON EXCHANGE MEMBRANE (PEM) FUEL CELLS. ENERGY DENSITY OF THIS RECHARGEABLE POWER SOURCE IS 6 TO 8 TIMES HIGHER THAN THAT OF RECHARGEABLE BATTERIES. THE HYDROGEN GENERATOR IS THE KEY… more
Abstract:The proton exchange membrane (PEM) fuel cell is being considered as power source for a variety of applications (1-4). Gravimetric and volumetric energy density, life cycle costs, ease and safety of operation are major considerations which may favor a PEM… more
Abstract:The need for environmentally clean sources of energy for vehicular propulsion is driving a worldwide effort to develop high energy density "supercapacitors". These electronic devices are expected to work in tandem with advanced batteries or fuel cells to… more
Abstract:The U.S. Army requires lightweight man-portable power supplies delivering approximately 300 W and weighing less than 5 kG. In this context we propose to develop a polymer electrolyte membrane hydrogen fuel cell with an ultra lightweight cell stack which can… more
Abstract:Proton exchange membrane fuel cells have gained much importance for providing electric power for vehicles and other portable powerplants due to their demonstrated excellent power density and fuel economies. They are particularly suited for man-portable… 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.
