  • Publication number: 20120171593
    Abstract: The present invention relates to a metal catalyst composition modified by a nitrogen-containing compound, which effectively reduces cathode catalyst poisoning. The catalyst composition applied on the anode also lowers the over-potential. The catalyst coupled with the nitrogen-containing compound has increased three-dimensional hindrance, which improves the distribution of the catalyst particles and improves the reaction activity.

  • Publication number: 20120168217
    Abstract: An embedded capacitor substrate module includes a substrate, a metal substrate and a solid electrolytic capacitor material. The solid electrolytic capacitor material is formed on the metal substrate, so as to form a solid electrolytic capacitor with the substrate. The embedded capacitor substrate module further includes an electrode lead-out region formed by extending the substrate and the metal substrate. The metal substrate serves as a first electrode, and the substrate serves as a second electrode. An insulating material is formed between the substrate and the metal substrate. Therefore, the embedded capacitor substrate module is not only advantageous in having a large capacitance as the conventional solid capacitor, but also capable of being drilled or plated and electrically connected to other circuits after being embedded in a printed circuit board.
