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

Description: 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. S… more

Cerium oxide coated anodes for aluminum electrowinning: Topical report, October 1, 1986-June 30, 1987

Description: Because of the cost of building and maintaining a carbon anode plant and the energy penalties associated with the use of carbon anodes in the production of aluminum, the use of inert anodes has long been proposed. Various cermet anodes have been investigated. In this paper, tests on a material, cerium oxyfluoride (CEROX), deposited in situ as an anode, are reported. (JDH)

Review of lithium-ion technology

Description: The first practical use of graphite intercalation compounds (GIC) as battery anodes was reported in a 1981 patent by Basu in which a molten salt cell was described having a negative electrode that consisted of lithium intercalated in graphite. A second patent by Basu, issued in 1983, described an ambient temperature rechargeable system which also utilized lithium intercalated in graphite as the anode. Work in this area progressed at a low level, however, until interest was sparked in 1990 when … more

Upgrading mild gasification liquids to produce electrode binder pitch. Final technical report, 1 September, 1992--31 August, 1993

Description: The objective of this program is to investigate the production of electrode binder pitch, from mild gasification liquids. The IGT MILDGAS process pyrolyzes coal in a fluidized/entrained bed to produce solid, gas, and liquid co-products. The largest market for pitch made from coal liquids is the aluminum industry, which uses it to make carbon anodes for electrolytic furnaces. In this project, crude pitch from the DOE-sponsored MILDGAS process research programs being modified by a flash thermocra… more

The LMF triaxial MITL voltage adder system

Description: The light-ion microfusion driver design consists of multiple accelerating modules fired in coincidence and sequentially in order to provide the desired ion energy, power pulse shape and energy deposition uniformity on an Inertial Confinement Fusion (ICF) target. The basic energy source is a number of Marx generators which, through the appropriate pulse power conditioning, provide the necessary voltage pulse wave form to the accelerating gaps or feeds of each module. The cavity gaps are inductiv… more

Determination of optimum electrolyte composition for molten carbonate fuel cells. Quarterly technical progress report, October--December 1987

Description: The goal of this program is the development of a molten carbonate fuel cell (MCFC) anode which is more tolerant of sulfur contaminants in the fuel than the current state-of-the-art nickel-based anode structures. This program addresses two different but related aspects of the sulfur contamination problem. The primary aspect is concerned with the development of a sulfur tolerant electrocatalyst for the fuel oxidation reaction. A secondary issue is the development of a sulfur tolerant water-gas-sh… more

NANOSTRUCTURED METAL OXIDES FOR ANODES OF LI-ION RECHARGEABLE BATTERIES

Description: The aligned nanorods of Co{sub 3}O{sub 4} and nanoporous hollow spheres (NHS) of SnO{sub 2} and Mn{sub 2}O{sub 3} were investigated as the anodes for Li-ion rechargeable batteries. The Co{sub 3}O{sub 4} nanorods demonstrated 1433 mAh/g reversible capacity. The NHS of SnO{sub 2} and Mn{sub 2}O{sub 3} delivered 400 mAh/g and 250 mAh/g capacities respectively in multiple galvonastatic discharge-charge cycles. It was found that high capacity of NHS of metal oxides is sustainable attributed to their… more

Novel Sulfur-Tolerant Anodes for Solid Oxide Fuel Cells

Description: One of the unique advantages of SOFCs over other types of fuel cells is the potential for direct utilization of hydrocarbon fuels (it may involve internal reforming). Unfortunately, most hydrocarbon fuels contain sulfur, which would dramatically degrade SOFC performance at parts-per-million (ppm) levels. Low concentration of sulfur (ppm or below) is difficult to remove efficiently and cost-effectively. Therefore, knowing the exact poisoning process for state-of-the-art anode-supported SOFCs wit… more

Electronic Circuits Lectures

Description: The two-electrode vacuum tube, or diode, consists of an electron-emitting cathode surrounded by a positive anode (plate). A plot of plate current (i{sub b}) vs plate voltage (e{sub b}) is shown. At low anode voltages, the anode current is limited by the repelling effect that the negative electrons already in the space have on the electrons just being emitted (space-charge effect). When a full space charge is present, the plate current depends upon the plate voltage according to Childs law: i{su… more

Spouted Bed Electrodes (SBE) for Direct Utilization of Carbon in Fuel Cells

Description: This Phase I project was focused on an investigation of spouted bed particulate electrodes for the direct utilization of solid carbon in fuel cells. This approach involves the use of a circulating carbon particle/molten carbonate slurry in the cell that provides a few critical functions: it (1) fuels the cell continuously with entrained carbon particles; (2) brings particles to the anode surfaces hydrodynamically; (3) removes ash from the anode surfaces and the cell hydrodynamically; (4) provid… more

Humectants To Augment Current From Metallized Zinc Cathodic Protection Systems on Concrete

Description: Cathodic protection (CP) systems using thermal-sprayed zinc anodes are employed to mitigate the corrosion process in reinforced concrete structures. However, the performance of the anodes is improved by moisture at the anode-concrete interface. Research was conducted to investigate the effect of hydrophilic chemical additives, humectants, on the electrical performance and service life of zinc anodes. Lithium bromide and lithium nitrate were identified as feasible humectants with lithium bromide… more
