Abstract:POLYMER ELECTROLYTE MEMBRANE (PEM) FUEL CELLS HAVE SEVERAL ADVANTAGES OVER CONVENTIONAL ELECTROLYTE FUEL CELLS. THEIR HIGH POWER DENSITIES MAKE THEM PRIME CANDIDATES FOR ELECTRIC VEHICLES, IN CONJUNCTION WITH A METHANOL REFORMER. HOWEVER, THE IMPURITIES… more
Abstract:… on storage batteries. This severely limits power density and causes the size of the unit to rise rapidly as the discharge time required increases, since most of the weight and size comes with the batteries. Replacing the storage batteries with a system consisting of a fuel… more
Abstract:Power requirements for manned U.S. spacecraft missions have been provided by fuel cells powered by cryogenic hydrogen and oxygen launched from earth. For long-term missions, propellant weight makes this approach prohibitive. Regenerative H2-O2 fuel cells have… more
Abstract:… VEHICLES (AUVS), SUBSEA ROBOTS, AND OTHER INSTRUMENTED AND REMOTELY OPERATED SYSTEMS FOR MARINE APPLICATIONS REQUIRE A POWER SOURCE WHICH IS AS EFFICIENT AS POSSIBLE TO GIVE LONG RANGE OR EXTENDED USE TIMES. THE OBVIOUS CHOICE IS AN ELECTROCHEMICAL UNIT OF FUEL … more
Abstract:At present, the only fuel cell systems that have the capability of achieving high power den W cm-2) are the proton exchange membrane (PEM) and the alkaline fuel cell (AFC) systems. Of these, the PEM system is the leading candidate fuel cell power source for… more

Abstract:… A NOVEL METHOD FOR THE FABRICATION OF THIN (20 TO 50) UM) NA-BETA-ALUMINA SOLID ELECTROLYTES. THIS METHOD, KNOWN AS ELECTROCHEMICAL VAPOR DEPOSITION (EVD) HAS BEEN USED SUCCESSFULLY TO DEPOSIT ZIRCONIA, PEROVSKITES, AND CERIA FOR APPLICATIONS IN SOLID OXIDE FUEL … more
Abstract:New solid polymer electrolytes (SPE's) based on Maxdem's rigid-rod polyphenylene resins are proposed for fuel cell application. The unique rigid-rod structure of the proposed ionomers is expected to lead to high proton conductivity in the absence of condensed… more
Abstract:… REAGENTS, AND WILL SAVE WATER AND POWER, BASED ON AN ELECTROCHEMICAL TECHNIQUE EMPLOYING ANION EXCHANGE MEMBRANES. THE CATHODIC REDUCTION OF OXYGEN TO PEROXIDE IN BASE HAS BEEN SHOWN TO BE HIGHLY EFFICIENT. THE INCORPORATION OF ANION EXCHANGE MEMBRANES IN A FUEL … more
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
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.
