    摘要： The present invention relates to a solar powered cathodic protection system using a photocatalyst which functions as a non-sacrificial photoanode under sunlight, wherein said non-sacrificial photoanode consisting of the photocatalyst such as TiO2 (or ZnO) and an electrolyte, is galvanically connected to a metal structure to be protected and continuously provides electrons to the metal structure, whereby the metal structure is protected from the corrosion. The solar powered cathodic protection system using a non-sacrificial photoanode according to present invention is advantageous in that 1) an external power supply is not necessary, 2) it is easy to maintain the system because the non-sacrificial photoanode according to the present invention can be installed outdoors, and 3) the photocatalyst used as the non-sacrificial photoanode is inexpensive and semipermanent.

    摘要： A metallic separator for a fuel cell with high corrosion resistance and low contact resistance without surface coating is provided. The separator for a fuel cell is formed by adding one or more of tantalum (Ta) and lanthanum (La) to an austenitic stainless steel that contains molybdenum (Mo) and tungsten (W).

    摘要： The present invention provides a separator for a fuel cell that comprises a metal substrate that contains at least one metal element M and a surface layer formed on a surface of the metal substrate and that contains at least one conductive oxide represented by LaMxO3 (wherein x=0 to 1). Also, the present invention provides a method for anti-corrosion treatment of a metallic separator for a fuel cell. The method involves first forming an La layer on a surface of a metal substrate having a desired dimension and a desired flow field formed therein. Next, the metal substrate having the La layer on its surface is heated such that at least one metal component contained in the metal substrate is diffused into the La layer and an La component in the La layer is diffused into the metal substrate to form a mixed layer composed of La and the at least one metal component on the surface of the metal substrate. Finally, the mixed layer is heated under an oxidizing atmosphere to form a layer composed of oxides containing La and the at least one metal component on the surface of the metal substrate.

    摘要： A metallic separator for a fuel cell including 2.2 to 6.0 parts by weight of tungsten based on 100 parts by weight of stainless steel containing molybdenum, and the weight ratio of molybdenum to tungsten (Mo/W) is 0.15 to 1.60. The separator for fuel cells has excellent anti-corrosive properties and contact resistance as low as that of a metal material, and thus, a fuel cell having high efficiency can be manufactured at a reasonable cost using the separator.
