  • Patent number: 8778562
    Abstract: A method of depositing a thin gold coating on bipolar plate substrates for use in fuel cells includes depositing a gold coating onto at least one surface of the bipolar plate substrate followed by annealing the gold coating at a temperature between about 200° C. to 500° C. The annealed gold coating has a reduced porosity in comparison with a coating which has not been annealed, and provides improved corrosion resistance to the underlying metal comprising the bipolar plate.

  • Patent number: 8771494
    Abstract: Systems and methods for the synthesis of lubricant-containing microcapsules are disclosed. Embodiments of composite nickel and copper coatings containing capsules with liquid lubricating oil cores are also disclosed. In certain embodiments, microcapsules can be incorporated into a metal plating solution to perform composite electrodeposition to obtain self lubricant metallic coatings. In some embodiments, much lower friction coefficient (˜0.8) and far better wear resistance was obtained with the copper/microcapsules composite.
