  • Selective area deposition and devices formed therefrom
    Publication number: 20080057687
    Abstract: Patterned thin film layers (12) are applied to a substrate (10) surface by masking selective areas of a substrate surface, e.g., with a printed pattern (11) of a material such as an oil, and vapor-depositing thin film material. The masking material is subsequently removed.

  • Fuel cell having improved catalytic layer
    Publication number: 20040185325
    Abstract: Catalytic layers for fuel cells are formed by co-depositing platinum or gold from a combustion chemical vapor deposition flame and carbon particles and ionomer from a non-flame, co-deposition flame. A layer having high platinum or gold loading with high particulate size is deposited. Such layers have high efficiency, whereby the total amount of platinum or gold used in a fuel cell may be reduced.
