    • PROBLEM TO BE SOLVED: To provide a separator seal for a polymer electrolyte fuel cell that has low permanent compression set, high strength of rubber itself, excellent formability and good adhesiveness with a separator substrate and imparts an excellent seal property for a long term, even under an acid atmosphere by an electrolyte membrane or in a state in contact with LLC.
      SOLUTION: Constituted is the sealing material for separator of polymer electrolyte fuel cell including: (A) polyorganosiloxane having alkenyl; (B) a copolymer resin comprising R
      3 SiO
      1/2 unit (R is a monovalent hydrocarbon group) and SiO
      2 unit as the main components, having the mole ratio of [R
      3 SiO
      1/2 /SiO
      2 ] of 0.5 to 1.5 and 5×10
      -3 to 1×10
      -4 mol/g of a vinyl group; (C) an organo-hydrogenpolysiloxane; (D) a fumed silica having 50 to 400 m
      2 /g of specific surface area by BET method; (E) carbon powder having 30 to 150 m
      2 /g of specific surface area by BET method; and (F) a catalyst for addition reaction, as the essential components. As a result, the separator seal for a polymer electrolyte fuel cell that has low permanent compression set, high strength of rubber, excellent formability and good adhesiveness with the separator substrate and therefore imparts an excellent seal property for a long term, even under the acid atmosphere by the electrolyte membrane or in the state in contact with LLC can be constituted.

    • PROBLEM TO BE SOLVED: To provide an improved technology of surface treatment of a fuel cell separator. SOLUTION: On a surface of a peripheral edge region of the fuel cell separator 10, a uniform and precise resin coat 30 is formed. However, the formed resin coat 30 may have defects 32 (minute holes). In a case in which the resin coat 30 includes defects 32, a metal coat 40 carries out coating on those defects 32. That is, when metal in complex ion is adhered to the fuel cell separator 10 by electrodeposition treatment, in addition to a power generation region, the metal is also adhered to a part where a surface (a surface of the separator base material) is exposed by the defects 32 of the resin coat 30, and a metal coat 40 is formed at the part of the defects 32. Therefore, as compared with the case in which the surface of the separator base material is exposed at the defect 32 part of the resin coat 30, corrosion resistance of the fuel cell separator 10 is improved.

    • 要解决的问题:提供燃料电池隔板的表面处理改进技术。 解决方案:在燃料电池隔板10的周缘区域的表面上形成均匀且精确的树脂涂层30。 然而,形成的树脂涂层30可以具有缺陷32(微小孔)。 在树脂涂层30包含缺陷32的情况下,金属涂层40对这些缺陷32进行涂覆。即,当复合离子中的金属通过电沉积处理粘附到燃料电池隔板10时,除了功率 金属也粘附在树脂涂层30的缺陷32露出表面(分隔体基材的表面)的部分,并且在缺陷32的一部分处形成金属涂层40。 因此,与树脂涂层30的缺损部32露出隔板基材的表面的情况相比,燃料电池隔板10的耐腐蚀性提高。 版权所有(C)2009,JPO&INPIT
