A hot-dip Zn&#x2014;Al alloy coated steel sheet exhibiting a beautiful coating appearance with metallic luster, in which no spangle or very fine spangles are formed, and having excellent blackening resistance and a method for manufacturing the hot-dip Zn&#x2014;Al alloy coated steel sheet are provided. The hot-dip Zn&#x2014;Al alloy coated steel sheet includes a hot-dip Zn&#x2014;Al alloy coating layer containing 1.0 to 10 percent by mass of Al, 0.2 to 1.0 percent by mass of Mg, 0.005 to 0.1 percent by mass of Ni, and the balance being Zn and incidental impurities on at least one surface of a steel sheet. The manufacturing method includes the steps of dipping the steel sheet into a hot-dip Zn&#x2014;Al alloy coating bath and pulling up and cooling the steel sheet, wherein the steel sheet pulled up from the coating bath is cooled to 250&#xb0; C. at a cooling rate of 1&#xb0; C. to 15&#xb0; C./sec.

Hot-dip Zn&#x2014;Al alloy coated steel sheet and producing method therefor

A stainless steel separator having gas channels including grooves and projections for fuel cells. The separator has a composition including about 0.03 mass percent or less of carbon; about 0.03 mass percent or less of nitrogen, the total content of carbon and nitrogen being about 0.03 mass percent or less; about 16 mass percent to about 45 mass percent chromium; about 0.5 mass percent to about 3.0 mass percent molybdenum; and the balance being iron and incidental impurities. The separator has a contact resistance of about 100 m&OHgr;&middot;cm or less. Preferably, the projections have an arithmetic average surface roughness Ra in the range of about 0.01 to about 1.0 &mgr;m and a maximum height Ry in the range of about 0.01 to about 20 &mgr;m. The stainless steel separator preferably further includes about 0.001 to about 0.1 mass percent silver. A fuel cell including this separator exhibits a stable output voltage for a long period of time.

This invention provides a laminated resin material comprising (1) a fiber reinforced thermoplastic resin layer made by a dispersion method, (2) a gas impermeable resin layer on the fiber reinforced thermoplastic resin layer, and (3) an adhesive resin layer having a melt viscosity of not more than 5000 Pa.s under a shear rate of 10 s at 150&deg; C. and not more than 250 Pa.s under a shear rate of 2000 s at 150&deg; C. on the gas impermeable resin layer. Among them, a laminated resin material in which the fiber reinforced thermoplastic resin layer made by the dispersion method is an expansion molded stampable sheet and which has a skin material further on the adhesive resin layer is a material excellent in both of the characteristics of adhesion and rigidity and suitable as automotive interior materials.

Laminated resin material

A fuel cell separator including (a) about 100 parts by weight of graphitized meso-carbon microbeads, (b) about 10 to 35 parts by weight of one of a thermosetting resin and a thermoplastic resin, and (c) about 1 to 40 parts by weight of at least one carbonaceous material selected from the group consisting of graphite powder, carbon black, and fine carbon fibers. The fuel cell separator exhibits low electrical resistivity, low volume resistivity, superior gas impermeability, and superior dimensional accuracy without a graphitizing treatment after molding. A fuel cell using the fuel cell separators can be produced while saving energy using a simplified facility and has superior generation efficiency.
