Design considerations for vehicular fuel cell power plants (open access)

Design considerations for vehicular fuel cell power plants

Fuel cells show great promise as an efficient, nonpolluting vehicular power source that can operate on nonpetroleum fuel. As with other power sources, design tradeoffs can be made that either improve vehicle performance or reduce the size and cost of the fuel cell power system. To evaluate some of these tradeoffs, a number of phosphoric acid fuel cell power plant designs have been studied to determine the performance level they would provide, both for a compact passenger vehicle and a 40-ft city bus. The fuel is steam reformed methanol. The analyses indicate that 1978 fuel cell technology can provide a 22 to 50% improvement in fuel economy over the 1980 EPA estimate for the conventionally powered General Motors X car. With this technology the city bus can meet the DOT acceleration, gradability, and top speed requirements. A reasonable advance in fuel cell technology improves performance and fuel consumption of both vehicles substantially.

Computational problems in magnetic fusion research (open access)

Computational problems in magnetic fusion research

Numerical calculations have had an important role in fusion research since its beginning, but the application of computers to plasma physics has advanced rapidly in the last few years. One reason for this is the increasing sophistication of the mathematical models of plasma behavior, and another is the increased speed and memory of the computers which made it reasonable to consider numerical simulation of fusion devices. The behavior of a plasma is simulated by a variety of numerical models. Some models used for short times give detailed knowledge of the plasma on a microscopic scale, while other models used for much longer times compute macroscopic properties of the plasma dynamics. The computer models used in fusion research are surveyed. One of the most active areas of research is in time-dependent, three-dimensional, resistive magnetohydrodynamic models. These codes are reviewed briefly.

Preparation and evaluation of advanced electro-catalysts for phosphoric acid fuel cells. Eighth quarterly report, October-December 1981. [Platinum] (open access)

Preparation and evaluation of advanced electro-catalysts for phosphoric acid fuel cells. Eighth quarterly report, October-December 1981. [Platinum]

In the development of new and highly efficient porous electrocatalysts, two cooperative phenomena are required. The first is an increase in the electrocatalytic activity of the catalyst particle, and the second is the availability of that electrocatalyst particle for the electrochemical reaction. These two processes interact with each other in such a way that improvements in the electrochemical activity must be coupled with improvements in the availability of the electrocatalyst for reaction. Since cost effective and highly reactive electrocatalysts have been developed under this program, the utilization of the electrocatalyst particles in the porous electrode structures is addressed. Based on the performance of the electrocatalysts in porous electrode structures, it is shown that a large percentage of the electrocatalyst in anode structures is not utilized. This low utilization translates directly and dramatically into a noble metal cost penalty for the fuel cell. Dramatic improvements in the cost effectiveness of the fuel cell will be achieved by improvements in electrocatalyst catalyzation technology and electrode structure technology.

Compact 36 kJ electron beam system for laser pumping (open access)

Compact 36 kJ electron beam system for laser pumping

An electron beam machine consisting of six modules is being constructed for the 'B' amplifier of the RAPIER KrF laser system. Each module consists of a diode, a 5 ..cap omega.. positive charged water dielectric Blumlein pulse-forming line, and a five stage Marx generator. Separate 25 cm x 41 cm electron beams are formed in magnetically isolated diodes which when arranged in groups of three produce two nearly continuous 25 cm x 125 cm beams that enter the laser cell from opposite sides. The pulse-forming lines operate at 450 keV and produce 150 ns long pulses. The lines employ electrically triggered annular SF/sub 6/ output switches. The two concentric transmission lines of each pulse-forming line are charged in 1 ..mu..s through symmetric circuits to reduce diode prepulse voltage. The six modules together with the laser cell will occupy less than 15 m/sup 2/ of floor space.

New approaches for the reduction of plasma arc drop in second-generation thermionic converters. Final report (open access)

New approaches for the reduction of plasma arc drop in second-generation thermionic converters. Final report

Investigations of ion generation and recombination mechanisms in the cesium plasma as they pertain to the advanced mode thermionic energy converter are described. The changes in plasma density and temperature within the converter have been studied under the influence of several promising auxiliary ionization candidate sources. Three novel approaches of external cesium ion generation have been investigated in some detail, namely vibrationally excited N/sub 2/ as an energy source of ionization of Cs ions in a DC discharge, microwave power as a means of resonant sustenance of the cesium plasma, and ion generation in a pulse N/sub 2/-Cs mixture. The experimental data obtained and discussed show that all three techniques - i.e. the non-LTE high-voltage pulsing, the energy transfer from vibrationally excited diatomic gases, and the external pumping with a microwave power - have considerable promise as schemes in auxiliary ion generation applicable to the advanced thermionic energy converter.

Large-area sheet task: advanced dendritic web growth development. Quarterly report, October 23-December 31, 1980 (open access)

Large-area sheet task: advanced dendritic web growth development. Quarterly report, October 23-December 31, 1980

Silicon dendritic web is a single crystal ribbon form of silicon capable of fabrication into solar cells with AM1 conversion efficiency in excess of 15%. Progress on a study to demonstrate the technology readiness of the web process to meet the national goals for low cost photovoltaic power is reported. Several refinements were introduced into the sensing and control equipment for melt replenishment during web growth and also several areas were identified for cost reduction in the components of the prototype automated web growth furnace. A new circuit has been designed, assembled and tested to eliminate the sensitivity of the detector signal to the intensity of the reflected laser beam used to measure melt level. Noise due to vibrations on the silicon melt surface has also been eliminated. A new variable speed motor has been identified for the silicon feeder. Pellet feeding will be accomplished at a rate programmed to match exactly the silicon removed by web growth. A system to program the initiation of web growth automatically has been designed and first tests initiated. This should eventually result in reduced labor content and improved process reproducibility. Potential cost reductions in the furnace chamber and storage reel have been identified. …

Ceramic phases for immobilization of /sup 129/I. [Sodalite and boracite] (open access)

Ceramic phases for immobilization of /sup 129/I. [Sodalite and boracite]

Materials for ultimate disposal of /sup 129/I have been studied. At present, iodide-sodalite, though not ideal, appears to be the best material for /sup 129/I immobilization from the aspects of ease of preparation, thermal stability, cost of materials, and leach resistance. Good consolidation of the material was achieved by sintering in air at 1000 to 1200/sup 0/C, but the iodine content was significantly below stoichiometric expectations. Hot aqueous media preferentially removed iodine, apparently by OH/sup -/ substitution in near-neutral solutions, and I reversible reaction Cl/sup -/ exchange occurred in brine. Alternation of the sodalite also took place. Soxhlet leach rates were about 5 x 10/sup -4/ g/cm/sup 2/-day by total weight loss, but physical weathering contributed significantly to this value. Moderate doses of radiation had no observable deleterious structural effects. Iodoboracites seemingly cannot be prepared by ceramic or nonhydrothermal wet chemical techniques. Fe-iodoboracite has inferior thermal stability to iodide-sodalite and was completely altered to hematite after treatment at 200/sup 0/C in deionized water. Silver zeolites retained some iodine in the form of crystalline ..cap alpha..-AgI at temperatures up to 1300/sup 0/C even though heating above approx. 700/sup 0/C altered the alumino-silicate framework. However, some of the iodine appeared to be …

Technical analysis of advanced wastewater-treatment systems for coal-gasification plants (open access)

Technical analysis of advanced wastewater-treatment systems for coal-gasification plants

This analysis of advanced wastewater treatment systems for coal gasification plants highlights the three coal gasification demonstration plants proposed by the US Department of Energy: The Memphis Light, Gas and Water Division Industrial Fuel Gas Demonstration Plant, the Illinois Coal Gasification Group Pipeline Gas Demonstration Plant, and the CONOCO Pipeline Gas Demonstration Plant. Technical risks exist for coal gasification wastewater treatment systems, in general, and for the three DOE demonstration plants (as designed), in particular, because of key data gaps. The quantities and compositions of coal gasification wastewaters are not well known; the treatability of coal gasification wastewaters by various technologies has not been adequately studied; the dynamic interactions of sequential wastewater treatment processes and upstream wastewater sources has not been tested at demonstration scale. This report identifies key data gaps and recommends that demonstration-size and commercial-size plants be used for coal gasification wastewater treatment data base development. While certain advanced treatment technologies can benefit from additional bench-scale studies, bench-scale and pilot plant scale operations are not representative of commercial-size facility operation. It is recommended that coal gasification demonstration plants, and other commercial-size facilities that generate similar wastewaters, be used to test advanced wastewater treatment technologies during operation by using …

Impurity study of TMX using ultraviolet spectroscopy (open access)

Impurity study of TMX using ultraviolet spectroscopy

An extreme ultraviolet (EUV) study of the emissions from intrinsic and injected impurities in TMX is presented. Two survey spectrographs were used to determine that the major impurities present were oxygen, nitrogen, carbon, and titanium. Three absolutely-calibrated monochromators were used to measure the time histories and radial profiles of these impurity emissions in the central cell and each plug. Two of these instruments were capable of obtaining radial profiles as a function of time in a single shot.
