Abstract: A direct antifreeze cooled fuel cell power plant is disclosed. The plant includes at least one fuel cell a thermal management system that directs flow of a cooling fluid for controlling heat within the plant, including a direct antifreeze solution passing through the water transport plate. The plant also integrates the direct antifreeze solution with a direct mass and heat transfer device, a water treatment system, and a steam injection system so that the direct antifreeze solution minimizes problems related to operation of the plant in sub-freezing conditions. A preferred antifreeze solution is an alkanetriol selected from the group consisting of glycerol, butanetriol, and pentanetriol. The direct antifreeze solutions minimize movement of the antifreeze as a vapor out of a water transport plate into contact with cathode or anode catalysts, and also minimize direct antifreeze solution loss from other power plant systems.

Abstract: A method and apparatus are provided for quantifying molybdate corrosion inhibitor concentrations in lithium halide brines of absorption refrigeration systems. This permits monitoring and control of the inhibitor level. A reagent is chosen for reacting with the molybdate in the brine to provide a readily identifiable characteristic color, the intensity of which is a function and measure of the molybdate concentration. The reagent is an acidified reducing agent which reacts to provide a significant characteristic color capable of optical detection without interference. In a lithium bromide brine, the molybdate concentration is conveniently identified by reaction with stannous chloride SnCl in hydrochloric acid Hcl (). The resulting color corresponds to a wavelength of about 550-560 nm (pink), and the intensity is a function of molybdate concentration. Portable measuring equipment, such as a hand held spectrophotometer, or colorimeter, provide a convenient means for making on-site measurements.

Abstract: A method of imprinting a workpiece includes lasing the workpiece to create a depression or other opening, depositing a laser-fusible polymer material into the depression, and then lasing the material so as to fuse the material into the depression. Preferably, the laser-fusible polymer material is fusible in the near infrared spectrum. An alternate method for imprinting using colored powder paints includes an additional step of heating the workpiece to ensure thermosetting of the colored powder paint. Laser fusible materials having particular physical characteristics and compositions may be used to facilitate the process.
