Abstract: Method and apparatus for measuring the permeability of polymer film materials such as used in super-insulation powder-filled evacuated panels (PEPs) reduce the time required for testing from several years to weeks or months. The method involves substitution of a solid non-outgassing body having a free volume of between 0% and 25% of its total volume for the usual powder in the PEP to control the free volume of the "body-filled panel". Pressure versus time data for the test piece permit extrapolation to obtain long term performance of the candidate materials.

Abstract: Integrated ethanol manufacturing by fermentation of biomass, with an electrical fuel cell generator of electrical and heat energy, the cogeneration including use by the fuel cell of the alcohol, and of the carbon dioxide from the fermentation, which increases the generation of energy, and use by the alcohol manufacturing of the heat and electrical energy from the fuel cell, which increases the fuel manufacture.
Abstract: The present invention is an improved method and related apparatus for quantitatively analyzing machine working fluids and other aqueous compositions such as wastewater which contain various mixtures of cationic, neutral, and/or anionic surfactants, soluble soaps, and the like. The method utilizes a single-phase, non-aqueous, reactive titration composition containing water insoluble bismuth nitrate dissolved in glycerol for the titration reactant. The chemical reaction of the bismuth ion and glycerol with the surfactant in the test solutions results in formation of micelles, changes in micelle size, and the formation of insoluble bismuth soaps. These soaps are quantified by physical and chemical changes in the aqueous test solution. Both classical potentiometric analysis and turbidity measurements have been used as sensing techniques to determine the quantity of surfactant present in test solutions.

Abstract: A manufacturing method for a separator plate for a molten carbonate fuel cell and separator plate made by the method. The separator plate comprises Ni-clad stainless steel. Aluminum is brought onto the wet seal area of the separator plate by high-velocity oxygen flame spraying. In addition, an intermetallic phase of the aluminum and the base metal is produced. The base metal can be both stainless steel or nickel.
Abstract: A catalyst assembly for placement in the anode compartment of an internally reforming fuel cell.
