75554-Due to the inherent inefficiencies of Proton Exchange Membrane (PEM) fuel cell stacks, a coolant must be used to remove the waste heat produced by the fuel cell. Deionized (DI) water or glycol/water solutions with a deionizing filter are commonly used as a fuel cell system coolant. Although… More

Due to the inefficiencies associated with Directed Energy (DE) weapons, a large amount of waste heat is generated that must be removed quickly to maintain a constant temperature operation. To remove such a high heat flux, an efficient heat transfer device/mechanism and a designer thermo-fluid are… More

75554B Fuel cells are an efficient, combustion-less, virtually pollution-free source of power. In particular, Proton Exchange Membrane (PEM) fuel cells are ideal for a number of applications, due to their ¿quick¿ warm-up characteristics. However, these fuel cells contain some inherent… More

Proposed is a robust, non-toxic corrosion inhibitor system consisting of novel, stable colloidal, hybrid polymeric or composite materials that are modified to have functional groups covalently or ionically combined with selected corrosion inhibition groups and are mainly prepared by atom transfer… More

The high degree of heat removal from directed energy (DE) weapons requires a next-generation leap in the performance of the heat transfer device/mechanism and also requires a novel thermo-fluid. Neither is available at this time. Nanofluids and Phase Change Materials (PCM) have been developed to… More
