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 radical polymerization. Chain length and number and type of functional groups can be adjusted. Hydrophobicity and other properties of the polymeric materials can be also modified. These polymers and their mixtures will be designed and formulated into a corrosion inhibiting package (with optimized corrosion inhibitor ratio, concentration and solubility) so that they can be easily applied to metal substrates from water or solvent solutions as pre-treatments, primers or coatings, to provide an innovative, versatile, robust, non-toxic corrosion inhibitor system. This novel inhibitor system can involve more than four-fold synergistic combinations of materials and functions, i.e., (1) polymer network + corrosion inhibitor(s), (2) corrosion inhibitor group A as inorganic oxoanions + group B as rare earth cations + group C as organic anions or compounds, (3) linear (co)polymer structures + core-shell polymer particles, and (4) adherent polymer protective barrier + hydrophobicity (repelling corrosive media), to achieve the desired corrosion inhibiting performances and other hybrid advantages over chromates.

The broader impact/commercial potential of this Small Business Innovation Research Phase I project is through the development of cost effective, high temperature molten salt heat transfer fluids for concentrated solar power plants that would make solar power an economical and viable source of renewable energy for mass consumption. With the worldwide growing need for energy, alternative sources of energy have been the primary focus of research over the past few decades. Molten salt heat transfer fluid used in concentrated solar power plants are one sub-area of such research. Molten salts have excellent stability at high temperature (>650C) and can be mined and easily manufactured into solar heat transfer fluids at a reasonable cost. Additionally, the developed molten salt heat transfer fluid would increase the efficiency of energy generation in solar power plants and provide potential cost savings by utilizing ubiquitous economical metals such as stainless steel. The heat transfer fluid could potentially bring the subsidy-free installed system price at the utility scale to a competitive price of 5-6 cents per kilowatt-hour.

The technical objectives in this Phase I research project are to (i) develop a fundamental understanding of interfacial corrosion of 316L stainless steel in molten chloride salt compositions and (ii) inhibit this corrosion by utilizing suitable additives. It is known that chloride salts could potentially increase the operating temperatures (to 900 Celcius) and hence enhance the energy efficiency of solar power plants. However, the extreme corrosive behavior of molten chlorides towards the stainless steel pipes utilized in solar plants has prevented their usage for practical applications. With the fundamental corrosion insight gained through this research project, Dynalene intends to develop proprietary inhibitor compositions that can be added to the chloride salt in-situ during the operation of a solar power plant. These additives would minimize corrosion by forming a continuous and inert ceramic layer at the operating temperature on the stainless steel surface, and simultaneo usly strengthen the grain boundaries. Dynalene had some initial success in growing a few micron-thick inert, continuous ceramic layer on a stainless steel surface. In this project, Dynalene will develop a corrosion package that would reduce dechromatization in steel and restrict the corrosion rate of 316L stainless steel to 10 micro-meters/year

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 inefficiencies, which results in waste heat that must be removed rapidly via a coolant ¿ currently, either Deionized (DI) water or glycol/water solutions with a DI canister. Although these coolants are non-flammable and thermally efficient, their electrical conductivity increases rapidly unless the DI canister is replaced frequently, which significantly increases capital and maintenance costs. This problem will be addressed by developing a novel Complex Coolant Fluid (CCF), comprised of a base composition and an additive package. The base composition addresses the non-flammability, thermal efficiency, freeze point, and materials compatibility issues, whereas the additive package maintains a low electrical conductivity in the CCF. In Phase I, key ingredients of the proposed additive package were prepared and incorporated into the coolant fluid. The resultant complex coolant fluid formulations were tested in two dynamic loops, and the additives were shown to maintain the electrical conductivity of the coolant below 2.0 microSiemens/cm for more than 325 hours. In Phase II, the additive package will be optimized and a more detailed study of the coolant performance and longevity will be carried out in a dynamic test loop that simulates fuel cell conditions. Optimized coolant samples will tested and validated in actual fuel cells under various operating conditions. Commercial Applications and Other Benefits as described by the awardee: The new complex coolant fluid should significantly expand the versatility of the PEM fuel cells in both mobile and stationary applications by offering the advantages of freeze protection, corrosion inhibition, and low electrical conductivity in a single aqueous-based fluid, attributes that are not available in competitive alternates. The commercial applications include, but are not limited to, automotive fuel cell engines, power generation for residential and commercial buildings, back-up power for hospitals and other emergency establishments, fuel cells used in ships and space vehicles, and mobile machinery and equipment.

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 these fluids are non-flammable and thermophysically efficient, the electrical conductivity increases rapidly, requiring frequent replacement of the deionizing filters and increasing fuel cell operating costs. This problem will be addressed by developing a complex coolant fluid comprised of a base composition and an additive package. The base composition addresses the non-flammability, heat transfer, freezing point, and materials compatibility issues, whereas the proposed additive package will maintain the electrical conductivity of the coolant below a certain level for 2 to 3 years. In Phase I, key ingredients of the additive package will be prepared and incorporated into the coolant fluid. The resultant complex coolant fluid formulations will be tested in a dynamic loop to determine the effectiveness of the additives in keeping the electrical conductivity of the coolant below 2 ?S/cm. Commercial Applications and Other Benefits as described by the awardee: The new complex coolant fluid should significantly expand the versatility of the PEM fuel cells in both mobile and stationary applications by offering the advantages of freeze protection, corrosion inhibition, and low electrical conductivity in a single aqueous-based fluid, attributes that are not available in competitive alternates.
