Abstract: A fuel reservoir having a reticulated material, generally a felt or a foam, disposed therein is provided. The addition of this reticulated material, either alone or in combination with a viscous fuel, assists the prevention of undesired flow of the fuel, the minimization of undesired leakages, and assists in orientation independence and uniform distribution of the fuel in the reservoir. The reticulated material enables the use of a viscous liquid fuel that has fuel diffusion rates and fuel utilization characteristics that approach those of neat liquid methanol. The material also helps create a greater surface area for evaporation, thus allowing a highly concentrated, vaporous fuel substance to be delivered to an associated fuel cell.

Abstract: The method includes sealing the stator bar end connections from within the stator bar end fitting. Particularly, a low viscosity epoxy is initially applied from within the chamber of the end fitting by use of a boroscope and a syringe-type applicator, the low viscosity epoxy being applied to all joints between the adjacent strands of the stator bar and between the fitting and the outermost strands of the stator bar. A high viscosity epoxy is then applied over the low viscosity epoxy using the boroscope and applicator to provide a thick barrier seal between the liquid coolant in the chamber and the brazing material. The epoxy is then cured. The process ensures that the brazing material is isolated from the liquid coolant by the barrier seal whereby potential leaks are prevented and partially developed leaks or leaks extant are arrested because sealant material is disposed at the liquid coolant/braze interface.

Abstract: A moving fluid containing pollutants including NOx compounds is subjected to a relatively low-power alternating-current dielectric discharge for a relatively long time duration. In this manner, pollutants are oxidized and dissociated while the temperature of the fluid is kept low enough to prevent the formation of new NOx pollutants.

Abstract: A method of increasing the adsorption resistance of a polymer having surface carboxyl or hydroxyl groups by directly contacting the surface of the polymer with an acylating agent under conditions sufficient to chemically react the carboxyl or hydroxyl groups with the acylating agent.
