    • Disclosed are a gas diffusion electrode for an electrochemical cell which comprises a catalyst layer formed by binding, by means of poiytotrafluoroethylene, catalyst-supporting carbon black and catalyst-non-supporting carbon black having a fluorinated polyolofine film on substantially whole surface, the catalyst layer being integrated on a substrate, and a process of preparing same. Since the carbon black employed for the formation of the gas network in the catalyst layer of the gas diffusion electrode having the above constitution in accordance with the present invention is completely hydrophobically treated, no electrolyte permeates this portion and the carbon black exhibits high hydrophobicity so that the wet-proofing is maintained even after the long operation period to enable the gas supply to the catalyst particles so as to provide the gas diffusion electrode with a long life and high electrode performances.
    • 公开了一种用于电化学电池的气体扩散电极,其包括通过聚四氟乙烯在催化剂负载的炭黑和在基本上整个表面上具有氟化聚四烯酚膜的催化剂不支撑炭黑结合形成的催化剂层,催化剂层 整合在基板上,以及其制备方法。 由于在根据本发明的上述结构的气体扩散电极的催化剂层中用于形成气体网络的炭黑被完全疏水化处理,所以没有电解质渗透该部分,并且炭黑表现出高的疏水性,因此 即使经过长时间操作,也能保持湿气保护,能够使催化剂粒子的气体供给,从而为气体扩散电极提供长寿命和高电极性能。

    • In a control system for a power transmission and distribution system, a plurality of distributed power supplying and receiving units each including a control unit are provided and connected along a power distribution line. The power supplying and receiving unit function to generate active and reactive powers of fundamental and higher harmonic waves to supply and receive the same to and from the power distribution line. A first central control unit controls the power distribution line and is designed to store information relating to the configuration of the power distribution line, to collect information with regard to instant open and close conditions of respective disconnecting switches connected for sectioning the power distribution line, and with regard to current electrical quantities on the power distribution line. Individual control command signals specific to the respective power supplying and receiving units are produced based on the stored and collected information and the respective power supplying and receiving units are controlled so that a desired target condition of the power distribution line is achieved autonomously within the power distribution line through an optimum cooperation control of the units.
