(USN) has developed an aqueous solution reaction (ASR) technique scalable for high volume production of nanostructured materials (n-materials) for a wide range of applications. By definition, nanophase materials have at least one physical dimension less than 10 nanometers (nm) in length, an attribute which imparts exceptional properties to them because the particle dimensions are close to atomic dimensions and there are a very high fraction of atoms residing at nanocrystalline grain boundaries. The high surface area of these materials has significant implications with respect to energy storage devices with electrochemical active sites (batteries, ultracapacitors) and energy conversion devices depending on catalytic sites or defect structure (e.g., fuel cells and thermoelectric devices). Potential application areas in both energy conversion and energy storage are discussed. Morphological studies of manganese dioxide have revealed the existence of both nanoporosity and mesoporosity within unusual superstructures comprised of nanorod building blocks. Nanophase nickel hydroxide has also been synthesized. Preliminary electrochemical studies are reported.","PeriodicalId":183668,"journal":{"name":"IECEC-97 Proceedings of the Thirty-Second Intersociety Energy Conversion Engineering Conference (Cat.

CO reduces the catalyst activity by blocking active catalyst sites normally available for hydrogen chemisorption and dissociation. The reaction kinetics at the anode catalyst surface can be used to estimate the decrease in cell voltage due to various levels of CO contamination in the inlet fuel stream. Literature data on the effects of CO-contaminated fuel streams on PEM fuel cell performance have been reviewed and analysed in an attempt to further understand the electrochemical properties of the CO adsorption process. A fuel cell performance model of a bipolar, Nafion 117 PEM fuel cell stack has been developed which predicts equilibrium cell output voltage as a function of current density and partial pressure of CO. The model contains both empirical and mechanistic parameters and evolved from a steady-state electrochemical model for a PEM fuel cell fed with a CO-free anode gas. Reaction kinetics and equilibrium surface coverage have been incorporated into the electrochemical model to predict the decrease in fuel cell performance at equilibrium. The effects of CO were studied at various concentrations of CO in hydrogen as the anode feed gas. Literature data were used to develop the model parameters and the resulting model is used to compare the model-predicted voltages, with and without CO, to data found in the literature.","PeriodicalId":183668,"journal":{"name":"IECEC-97 Proceedings of the Thirty-Second Intersociety Energy Conversion Engineering Conference (Cat.

A stretched laminar tubular flame was established by injecting a lean gaseous fuel air mixture uniformly in the radial direction from a central porous tube into an annular combustion space formed by an outer tube. Measurements of concentrations of major gaseous species using sampling and chromatography and temperature using thermocouples and an infrared pyrometer revealed that all scalar properties are independent of distance along the tube in this novel burner. Multi-fuel capability including military logistics fuels will make the present burner even more desirable. A modification that will keep the system self sufficient and will not require the use of pressurized or ultrasonic atomizers for liquid fuel combustion is presented. The design of a power system that integrates this novel burner and counterflow recuperator with alkali metal thermoelectric converter (AMTEC) cells to produce 200 W of power with overall efficiencies between 14% and 18% is also conceptually demonstrated.","PeriodicalId":183668,"journal":{"name":"IECEC-97 Proceedings of the Thirty-Second Intersociety Energy Conversion Engineering Conference (Cat.
