  • Publication number: 20150299628
    Abstract: The present invention proposes a method for removing an oxide formed on the surface of a copper film used in the process of manufacturing a circuit for a semiconductor, an organic light-emitting diode, an LED, or a liquid crystal display without causing corrosion on a lower metal film. The composition including corrosive amine may remove a metal oxide depending on the content of additive ranging from 0.01 to 10% regardless of the content of ultrapure water. A polar solvent other than the corrosive amine may efficiently remove an oxide from the surface of the metal when the same contains water and 0.01 to 20% of the additive.

  • Patent number: 9160023
    Abstract: The present invention relates to an electrolyte-impregnated, reinforced matrix for molten carbonate fuel cells and a manufacturing method thereof. According to the invention, the electrolyte-impregnated matrix, which comprises both the electrolyte and the reinforcing particles including a metal and an oxide, is manufactured by adding the electrolyte, as required per unit cell of a fuel cell, and the reinforcing particles including the metal and the oxide, to a slurry during the matrix preparation step, and subjecting the resulting slurry to a tape casting process. By doing so, the matrix stacking operation is facilitated, and the matrix manufacturing process is simplified. In addition, cracking caused by the difference in thermal expansion coefficient between an electrolyte sheet and the matrix can be suppressed, and thermal shock occurring during operation of the fuel cell stack can be reduced, thus improving the performance and lifetime of the fuel cell.
