    • Disclosed are a method of producing a fuel cell separator. In this method, dry granules of a composition for a fuel cell separator mainly containing a conductive material, a binder, and an additive are produced by mixing raw materials including at least the conductive material, the binder, and the additive, granulating the resultant mixture to obtain granules, and drying the granules. The dry granules may be further sized. Then, the granules are packed in a mold, and hot-press molded. This method is characterized in that the granules have a residual volatile matter content in a range of 4 wt % or less, and an average particle size in a range of 200 to 700 nullm (60 to 160 nullm for the sized granules) and a specific particle size distribution. With this method, a fuel cell separator having a high elasticity, an excellent dimensional accuracy, and a high gas non-permeability can be produced with no molding failures, accordingly, with a uniform quality. Further, a solid polymer electrolyte fuel cell having a high gas sealing characteristic and an excellent impact resistance can be produced by using the above high quality fuel cell separators as part or all of separators in the fuel cell.
    • 公开了一种制造燃料电池隔板的方法。 在该方法中,通过混合至少包含导电材料,粘合剂和添加剂的原料,将主要含有导电材料,粘合剂和添加剂的燃料电池隔板用组合物的干燥颗粒混合,将所得混合物 得到颗粒,并干燥颗粒。 干颗粒可以进一步定尺寸。 然后,将颗粒包装在模具中,并进行热压成型。 该方法的特征在于,所述颗粒的残留挥发物含量为4重量%以下,平均粒径为200〜700μm(尺寸为60〜160μm的颗粒)和特定的 粒度分布。 利用这种方法,可以制造具有高弹性,优异尺寸精度和高气体非磁导率的燃料电池隔板,而不会造成模制故障,因此具有均匀的质量。 此外,通过使用上述优质燃料电池隔板作为燃料电池中的一部分或全部隔板,可以制造具有高气体密封特性和优异的耐冲击性的固体聚合物电解质燃料电池。

    • The present invention discloses a recording material in which an ink receiving layer containing, as main components, a binder resin and microparticle silica is provided on a substrate, wherein a ratio F/R, which is a ratio of a solid content weight F of the microparticle silica in the ink receiving layer to a solid content weight R of the binder resin, is in the range of 2.0 to 7.0 and a dicyandiamide polycondensate is contained in the ink receiving layer. The recording material of the present invention has excellent water proof and light resistance properties and allows printing of full-color images thereon without the patterns, colors, texture of the substrate material surface being marred even when an ink receiving layer is provided on the substrate. The recording material can be suitably used not only in the ink jet type recording but also in the offset printing.
