  • Publication number: 20160299400
    Abstract: Potential non-uniformity in a surface of an electrode in an electrochromic element is improved during coloring and color erasing. The electrochromic element includes a pair of transparent electrodes and an electrochromic layer placed between the transparent electrodes. Each of the transparent electrodes includes an end portion having an electric supply portion. The electric supply portions face each other. The surface resistivity of each of the transparent electrodes increases with the increase of the distance from a corresponding one of the electric supply portions. The potential of the transparent electrodes is such that the difference between the maximum and minimum potentials in a surface of each transparent electrode is less than or equal to a predetermined value.

  • Patent number: 8722220
    Abstract: Provided is a hydrophobic catalyst layer for a polymer electrolyte fuel cell to which hydrophobicity is imparted so that the dissipation property of produced water is improved and which simultaneously has an increased effective surface area and an increased utilization ratio of a catalyst, and a method of producing the same. The catalyst layer for a polymer electrolyte fuel cell includes a catalyst obtained by reducing a platinum oxide, a hydrophobic agent, and a proton conductive electrolyte, wherein the hydrophobic agent is mainly composed of alkylsiloxane. An Si compound containing a hydrophobic substituent is brought into contact with a platinum oxide to subject the Si compound to hydrolysis and a polymerization reaction by the catalytic action of the platinum oxide, and then it is reduced, thereby obtaining a hydrophobic catalyst layer carrying an alkylsiloxane polymer.
