Abstract:POLYMER ELECTROYTE MEMBRANE (PEM) FUEL CELLS ARE PROMISING CANDIDATES FOR LOCALIZED POWER GENERATION AND TRANSPORTATION APPLICATIONS BECAUSE OF SIMPLICITY OF DESIGN, LOW WEIGHT, AND LOW TEMPERATURE OPERATION. ALTHOUGH HYDROGEN BASED PEM FUEL CELLS ARE… more
Abstract:…ement. Waste is fed into a oven where the steam-reforming produces light hydrocarbons that are then pulled into the higher temperature electrically heated reactor where superheated steam is added to destroy the waste nearly completely and produce syngas which can power a fuel… more
Abstract:A PROGRAM FOR THE DEVELOPMENT OF A HYDROGEN GENERATOR FOR USE WITH PEM FUEL CELLS IN UUV APPLICATIONS IS PROPOSED. HYDROGEN IS GENERATED BY REACTING ALKALI AND ALKALIEARTH METAL HYDRIDES WITH WATER. PURE HYDROGEN AND ALKALI-ALKALI EARTH METAL OXIDES OR… more
Abstract:THIS PROJECT OFFERS A SOLUTION TO THE PROBLEM OF PROVIDING ELECTRICAL POWER AT REMOTE LOCATIONS IN POLAR ENVIRONMENTS. A PROTON EXCHANGE MEMBRANE FUEL CELL OPERATING ON STORED HYDROGEN AND AMBIENT AIR CAN OPERATE UNATTENDED FOR SIX MONTHS OR MORE. THE EFFORT… more
Abstract:Busek Co. herein proposes a new fullerene synthesis process which was experimentally demonstrated and involves plasma breakdown of suitable hydrocarbons. The byproduct of the synthesis is hydrogen that can be sold or used on site for fuel cell based… more
Abstract:Fuel cells are being considered by the Army for future individual soldier power supplies. These power units are to be lightweight, compact and suitable for use on the battlefield. A compact, lightweight, safe source of pure hydrogen (and possibly oxygen) is… more
Abstract:… of a disposable syringe. Initially, the battery and circuit will be umbilically attached to the adaptor. In Phase II, an autonomous self-contained prototype product will be developed and manufactured for bench and clinical testing. We will take NASA-developed fuel … more
Abstract:THE OBJECTIVE OF THE PROJECT IS TO DETERMINE THE UTILITY OF SOLID OXIDE FUEL CELLS (SOFCS) FOR PROMOTING THE EFFICIENT ELECTROCHEMICAL CONVERSION OF METHANE-BASED FUELS TO ELECTRICAL ENERGY OVER THE TEMPERATURE RANGE 600-900 DEGREES CENTIGRADE. EMPHASES IS IS… more
Abstract:THIS PLANNED PROGRAM WILL BE DIRECTED TOWARDS DEVELOPING THE SCIENTIFIC AND TECHNICAL INSIGHT NECESSARY FOR EVALUATING AN INTERMEDIATE TEMPERATURE FUEL CELL FOR PROMOTING THE HIGHLY SELECTIVE CONVERSION OF NATURAL GAS TO ETHYLENE IN ITS ANODE COMPARTMENT.… more
Abstract:… ALL APPLICATIONS. ZINC FERRITE ALSO CANNOT REMOVE SUBSTANTIAL AMOUNTS OF HYDROCHLORIC ACID (HC1), WHICH IS THE SECOND MOST DETRIMENTAL TRACE SPECIES AT UP TO 500 PPM IN COAL-GAS. UNTIL NOW, THE PRODUCTION OF A COAL-GAS COMPATIBLE WITH GAS TURBINE, DIESEL ENGINE, AND FUEL… more
Abstract:… PROCEDURES FOR MOLDING BIPOLAR PLATES WITH DESIRABLE PHYSICAL, CHEMICAL, AND ELECTROCHEMICAL PROPERTIES FOR USE IN ACID-CONTAINING APPLICATIONS UNDER OXIDIZING CONDITIONS. THE EFFECT OF MOLDING CONDITIONS ON BIPOLAR PLATE PROPERTIES AND THE USE OF THE PLATE IN FUEL … more
Abstract:POLYMER ELECTROLYTE FUEL CELL (PEFC) TECHNOLOGY HAS GREAT PROMISE FOR THE ELECTRIC VEHICLE. HOWEVER, STATE-OF-THE-ART TECHNOLOGY CURRENTLY REQUIRES CATALYST LOADINGS OF EXPENSIVE NOBLE METALS SUCH AS PLATINUM (PT) AT COSTS WHICH HINDER ECONOMIC VEHICULAR… more
Abstract:… DURABLE HUMIDITY SENSOR, WHILE THE SHORTCOMINGS ENCOUNTERED WITH HYDROCARBON-BASED POLYMERS ARE OVERCOME BY USING HIGHLY STABLE PROTON-CONDUCTING FLUOROCARBON POLYMER MATERIALS. THESE MATERIALS HAVE AN ESTABLISHED PERFORMANCE RECORD IN ELECTROCHEMICAL SYSTEMS, E.G., FUEL … more
Abstract:…. However, the power and energy density requirements of the new devices are very large and are at the limit, or exceed, the best battery technologies available today. The objective of this project is to determine the feasibility of using a lightweight, high power density, 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.
