摘要： Disclosed is a reflective film laminate, which has a pure Ag film or an Ag-based alloy film as a first layer on a base body, and an oxide film of a metal of one or more kinds selected from among Zr, Cr, Nb, Hf, Ta, V, Ni, Mo, W, Al and Si, as a second layer on the first layer. The thickness of the second layer is 0.1 to 10 nm, and deterioration of the reflection ratio of reflective film laminate is 30% or less by having the second layer provided therein. The reflective film laminate is provided with a protection film, which has a high initial reflection ratio, excellent sulfuration resistance and heat resistance, and an extremely small number of pin holes. As a result, the reflection ratio of the reflective film laminate is not easily deteriorated due to aggregation of Ag atoms of the Ag film.

摘要： A separator for a fuel cell comprising a titanium alloy substrate containing at least one noble metal element selected from platinum group elements, Au and Ag; and a layer of a mixture formed on the titanium alloy substrate, said mixture comprising the noble metal element precipitated from the titanium alloy substrate and titanium oxide, and said layer having an average thickness of up to 200 nm; wherein the mixture layer on the surface and the titanium alloy substrate have a conductivity in terms of contact resistance as determined by the following method of up to 12 mΩ·cm2. The contact resistance is determined by placing a carbon cloth having an average thickness of 0.3 mm on opposite surfaces of the titanium alloy substrate having the mixture layer formed thereon; sandwiching the titanium alloy material with a pair of copper electrodes via the carbon cloth, the copper electrodes each having a contact area with the titanium alloy material of 1 cm2; measuring voltage drop between the carbon cloths by using a four terminal ohmmeter while pressing the copper electrodes against the titanium alloy material at a surface pressure of 5 kg/cm2 by using a hydraulic press and applying an electric current of 7.4 mA between the copper electrodes; and calculating the contact resistance from the measured value.
